Yep. The reason most companies don't use optical encoders is the battery life hit
Also logitech is coming out with the superlight 2 DEX, seems like a big shape up your alley. No idea if it'll have optical encoder or not yet
If you can extend your budget a bit I'd recommend the keychron m6 https://neomacro.in/products/keychron-m6
While it doesn't have optical switches, the huanos used in it are very reliable switches.
Unfortunately since you want a mouse that fills your hand and budget restraints the newer razer...
These will also fail, ttc silver/kailh ge's are not the most reliable encoders. But when they fail will be entirely upto luck, can be 1 month 1 year 2 year. Some mice are coming with optical scroll encoders now, they are least likely to fail.
Also there is 1 year warranty so you can get it...
Switches are the same on both r1 and r1 pro, transparent blue shell pink dots. These are most widely used in many today. They are very good.
The scroll encoder is different in the r1 pro, While it is better it is not a huge difference. Mostly comes down to durability which can sometimes come...
The r1 has an inferior mcu(microcontroller) which results in lower efficiency hence lower battery life and some polling rate instability. Although its mostly fine if you dont mind the lower battery life. The r1 doesnt have a coating, r1 pro has a coating similar to lamzu and gpx.
R1 pro only has...

If you mean the quality of the mouse itself then its night and day. R1 pro has a better coating, much better build quality, better mcu which in turn increases battery life and polling rate stability. Also the software is 10x better. R1 pro has both web and app based software.
As for the shape...
While they might look similar at a glance, they feel very different in hand. U2 is overall narrower feeling. Front flairs differently and side curves are a bit different. Use rtings 3d tool if the mice are available there instead of eloshapes as 3d view is much better to understand the...
I've mentioned in the warranty section. I'll do it here aswell. Only the Zowie U2 and the Logitech Superlight 2 are in warranty out of these and invoices for both are attached

I would not recommend the crucial p3+, it has tbw rating of 220tb only. While the competition has 600 or more. I would suggest going with SN 770 or XPG S70 blade.
Or if you have the budget then the 850x or kc3000(on sale)
