If packing space, weight, and cost are all no issue - then the Exped Megamat is the top choice for comfort and warmth.
For me, it was too big to pack so I opted for the Big Agnes Campmeister deluxe XLW (extra long and wide) - packs down tiny, really comfortable, and insane thermal value I think R value 7
Get something with 4 inchs of thickness. Us big guys need that level or near to it of thickness. Nemo Quasar is close, same with Big Agnes Campmeister. I have the Thermarest neoloft and love it. I'm also a big guy.
Thermarest and definitely the Campmeister are good for those temps.
Big Agnes Campmeister or the Exped Megamat Ultra. Both are comfy and you can really spread out. Neither is light, but both are worth taking for good sleep.
The campmeister has zero support in the center unless it's inflated super tight. I returned it after one trip.
The Exped Megamat Ultra has been warm for me down to 20F/-7C. I haven't tested it below that. It's much more comfortable than the campmeister too.

Car camping comfort champ, but some side sleepers find it thin.
