The biggest difference between the two is CoreXY vs CoreXZ. CoreXZ printers like Prusa MK4 are useless in my opinion. Constant bed side to side movement causes your model to vibrate and this vibration amplitude increases with every layer. That means you either have to print everything very slowly or limit yourself to very short models. You’re also missing out on cooling performance.
If you’re looking for an actual upgrade, I’d recommend looking away from bed slingers. Please note that I’m not saying that you should buy any Bambu products, just don’t buy bed slingers.

I have a very old photo printer from Canon and it’s amazing! Produces really high quality photos in A3. And I’ve never had any issues apart from two nuances: it can’t print text documents and its ink is very very expensive. Not your average inkjet expensive, it’s much more expensive and it lasts for like 20 full page prints or something.
On the other hand you’re not getting full colour high quality A3 prints cheaper in a photo lab either. And your average photo lab can’t print photos that good.
I use Copymaster3D PLA most of the time. It’s cheap and locally made. It’s not the best (some colours have some inconsistency issues and white PLA has some crap inside), but it works for prototyping and is very dimensionally stable. I also use their Tough PLA for final parts, it’s more expensive, bit it’s very consistent and prints nicely at higher speeds. Actually it’s main issue is that it’s too leaky so you can’t print it slow - it just sips on its own.
There are recycling services in the UK, but I have no clue about US.
