FuelCell SuperComp Trainer v3

No opinion on two pairs needed but I did just snag a second pair of NB SuperComp trainers (they have a plate) from https://www.newbalance.com/pd/fuelcell-supercomp-trainer-v3/MRCXV4-48670.html?dwvar_MRCXV4-48670_style=MRCXCG4 For $115 with their make an account and get an extra 20% off...

If the Nimbus works well for you I would start with one of those first and see if that feels right for you still. I ran my fastest races in the Nimbus range (1h 35m for a half, 42m for a 10k). Theres nothing wrong with them if they work for you. I would possibly rule out carbon plate shoes because as you say you are on a budget and those may be beyond your reach. You may get lucky in some sales though so always worth searching around. It's very difficult to recommend running shoes for people because we are all different and of course built differently as well. I run in the NB Supercomp Trainer V3. A shoe that is universally hated by most running shoe "geeks" lol. However it works very well for me, I can get into a good 5.30 minute per km pace, and I regularly finish half marathons in under two hours in them. The cushioning protects my body and every half marathon I've done in them I feel great the next day. My only complaints are I wish they were a tiny bit lighter, and they had a bit more rubber on the sole. I loved the V1's but the sole rubber was so soft you could wear through it in 400 miles and the V3's are kind of similar. I don't like Nike, I've tried various models, most are too soft for me, or they fall apart after 100 miles, etc. However, I can understand why people like them. I tried both the Vomero and Invincible shoes (too unstable) and hated them. Again we are all different my friend. I recently purchased the Asics Megablast, really fun running shoe. Great bounce, energy and I could see me smashing my times in them BUT they cause me foot pain due to the narrow foot box so they are going on EBay unfortunately! Because the Megablast has become so incredibly popular you can find the Superblast on sale on some websites. If you get on well with ASICS maybe those are worth a try (if they are within you budget). As mentioned the Mizuno Neo Vista is very well regarded and are often found for great prices online. I got myself a pair of the Neo Vista 2's for less than $100. The reviews comparing them to the original Supercomp Trainer got me interested so I'm waiting for the weather to improve a bit before trying them. They are nice and white at the moment and I want to try and keep them bright and shiny at least for a little while! haha. Good luck on your search, find a good running store if you can and try on a few different pairs from various brands. Don't let them put you under pressure to buy. Sometimes you can be surprised by what works for you.

ASICS Yogiri NB Super Comp Elite V4 NB Super Comp Trainer V3 I'm a 3:46 marathoner and have really bad hypermobility, so even though I work hard in the strength department, I can't take any risks with my shoes, and have found all three of these to be good. These also fit orthotics in them, which I couldn't do with the Hoka Rocket. The NB Elite is the most 'poppy' fastest feeling of them, with the Yogiri a lovely shoe for tempo runs and the NB Trainer a great long run shoe.

Trainer v3 fits so much tighter in the same wide size as my trainer v1s did. The sock like upper was a godsend for wide feet

I returned these for the same concerns without running in them and got the NB SuperComp Trainer V3s instead - soooo much better. They feel phenomenal to me and have great energy return.

You could check out the new balance SC trainer V3. I feel it’s pretty stable but still has some good energy return

Our paces and dimensions are quite similar (21:56 5K, 1:43 HM, targetting a 3:29 marathon at 7:55/mi, 6'1" 185 lb) so I feel like I can chime in! For tempo work I've run through the Zoom Fly 6 and New Balance SuperComp Trainer v3s for the last season and it feels like that's the perfect comfort shoe combo for me. I've raced in the Zoom Fly 6 and (beyond some heel stability lacking) they've been brilliant through all paces. I primarily use the Zoom Fly 6 for the interval and track speed work, while I use the SC Trainer v3s for my marathon paces for that extra stability. I think you're good to race in the SB2s for sure, but the Zoom Fly 6 to create a rotation and prevent wearing the shoes out (if budget allows) can be a good idea. I've trained in the Magic Speed 4 for about 50-ish miles and had to return them because of some serious patellar discomfort they give me. Best of luck in your shoe choice!
