I think that for different budgets, here are my recommendations:
Budget: QiYi MS
Midrange: DaYan GuHong Pro 54mm Maglev
Midrange (alternates): QiYi Valk 3 M, DaYan TengYun V1
Baller: GAN Mini M Pro
My personal favorite: QiYi Valk 3 M
Some cubes that are good for OH include the YS3M BC (Max Park uses this,) RS3M V5 BC (Considered the "best" OH cube), DaYan GuHong Pro (spring or maglev preferably 54 or 55mm,) QiYi Valk 3M, Gan Mini M Pro (Last time I saw J perm uses this,) WRM v9 BC and the Tengyun v1.

I would recommend the PiCube WRM V9 over the regular V9 BC, the magnets I feel are too strong in the regular version. I like it for 2-handed but it doesn't work for OH in my opinion. It's also on sale for $40 on TheCubicle instead of $44 right now.
For me, i used the rs3 super v2 standard, Because out of the box it was already loose and tight at the same time and it reminded me of the rs3 v5
But, the top OH solvers in my country use the ys3, and the Super Rs3 v1
