Help me choose... Please

Decided to get myself a new keyboard and have narrowed it down to either of these two..

M75 newer version with South facing LEDs, brown switches, cherry profile R75 wired version with silver switches, MDA profile

Would probably use it wired primarily but like the versatility of being able to go wireless. The software looks like it would be good for macros and changing the lighting. Though I do prefer the look and feel of the MDA keys and the silver switches (love the sound of them tbh).

I'm classed as being a high functioning autistic (Asperger's) and do love stuff to fidget with so I'm kinda torn between them.

The thing that worries me about the M75 is reliability after seeing quite a few posts on this sub about them failing.

Forgot to mention that they are both very close to each other price wise, £60 for the M75 and £56 for the R75, both from Amazon UK.
