Mk 3/4 , Gecko g540? Looking to upgrade from X pro V2

Hello,

I am looking to upgrade the board and interface for my nema 23 3-axis machine. My main focus is reliability. I need something that can run for hours at a time doing light work in the shop. I killed my X pro v2 and want something that can handle more abuse.

I have searched all over for a solution, however i keep coming up with mixed reviews, opinions, etc.

What do you guys recommend for someone wanting to move away from an all-in-one board?

Thanks!
