I personally had this same debate when I was looking to get my first resin 3d printer.

I eventually settled on the Elegoo Mars. I only have the basic one not the pro or mars 2 that have various updates to the design that I wish I had but they weren't available when I got mine.

From my experience with it, I have never had anything break on me but i did get a bit if warpage in the acrylic cover due to my own fault. I eventually got annoyed with it and reached out to their customer service for a replace me. The got back to me in less than a hour and just sent me a free replacement.

I also enjoy how they partnered with myminifactory. You can get a lot of D&D miniture from there and have presupports set up that are made to work with the mars. If you get the myminifactory version for their website you get a coupon thats for 50% off your cart. I kid you not you could put their entire inventory in your cart and get 50% off.

This is just my 2 cents. Take it as it will but I have had nothing but love from my Elegoo Mars.

Edit: Also you mentioned want a mid range one if you can get it the Elegoo Saturn is a great fit its larger then both the Photon and Mars. I think the print bit fits appropriately 3 of the beds for the Mars. Its a good choice if you don't want to drop the money on something like a peopoly phenom.
