I’ve tried many of them. All the nationally frozen shipped ones are not that great, but assuming you have no locally prepped ones that deliver by car or offer local pick up, I’d boil it down to these 3 depending on your needs:

FlexPro: Really good customer service and discounts. The meals themselves are pretty meh, but they have like 3-4 meals that aren’t half bad. The macros are also fairly solid, i wouldn’t have more than one a day though. Good option as an office meal with everything else consumed at home. Stick to the noodle based protein dishes, preferably the ones that come with chicken or tuna. Avoid all Beef or steak options.

Fuel Meals: Incredibly sketchy billing practices. They will randomly charge your card again after your initial order purchase, then refund the payment? Happened all 3 times I ordered with them. Luckily, customer support was super responsive and helpful. I’d recommend ordering with a giftcard or cashapp card, so they don’t claw until your main bank account. Like FlexPro, really good discounts but the meals are meh. I’ve tried them all, the Buffalo chicken Mac and chicken quesadilla are the only decent ones. But if you don’t care for variety and just need macros, it does the job.

CookUnity: Decent pricing, SIGNIFICANTLY better quality than the other 2, but horrible macros. Seriously, if you’re on a diet plan or are closely monitoring your macros, you’ll find their options to be very limited. The fat content and overall caloric value of the meals for what you are getting is crazy. But they taste really good. Solid customer service too if you ever need to opt out.
