GO

Built in PID. Temp gauge. Adjustable pressure. Profitec Go had all of these and I love it.

I think the only reasonable upgrade is a Gaggia Classic EVO PRO or if you can find a used profitec go. Just be aware that you’ll most likely need a bunch of new accessories since these are 58mm compared to 54mm. If you’re happy with the bambino plus and had no complaints then get a new bambino plus since it’s on sale right now.

Had the gaggia and switched to Go last Christmas.. If the budget permits, go for profitec. I like the PID control for consistency

I recently upgraded from a Profitec GO to a Linea Micra, and couldn't be happier. The single boiler workflow was getting very annoying, even with the GO being quick. I got the Micra for $5600 CAD. It's expensive, but I'm sure it's going to last a very long time. They don't offer any flow control, which is not an issue for me since I was looking for an easy workflow that produces good coffee. The Micra delivers that for sure.

I wouldn’t get this machine or breville/sage machines. I had sage barista pro and it’s group head leaked water, apparently its screws lose and I opened it up put some lock tide, it worked for a while but it did it again, I sold it for a very low price just to get rid of it. It is an appliance not a machine, it will break eventually. I got a Profitec Jump amd Eureka perfetto grinder, it was sold as a pair with discount. I realized the how high quality can a machine could be. For a lower price, I would get Profited Go and a eureka grinder (or other decent grinder) usually it is sold as paired with a nice discount. You would thank me later.

Gaggimate/Gaggiuino>Profitec Go>Gaggia in objective capability. Gaggia out of the box is great for Italian style espresso, but I found it lacks the control needed to properly enjoy a larger variety of espressos (eg lighter roasts). Profitec Go seems nice, and I almost bought it myself but went with Gaggia to save space. I’m glad I did because I then did Gaggimate, and the pressure/flow profiling plus temp control, brew by weight, etc etc far outdoes the Profitec for about the same price. Basically gives you capabilities similar to a $4k Decent. The mod does require some effort, but I think anyone can do it and there’s an active Discord if you need help. Be sure not to cheap out on the grinder either - DF54/64 are a really great value, aside from a few exceptions most cheaper grinders are not good enough to make good espresso.

Profitec Go is a solid buy. You need to spend a decent amount of money on a grinder too. I've got a Baratza Sette 270wi which is great for workflow as it grinds into the portafilter and grinds to weight, but it's a bit plasticy and incredibly loud. Would probably get a Niche Zero grinder if I could turn back time.
