Best MTB brakes for self-servicing & reliability

[Fisan]

As per title, which MTB brakes in your opinion are the easiest to to self-service? Preferably lower end market.

[Steady Spin]

Sadly not the lower end market but Hope is insanely reliable and easy to self service. 
I've bled mine once in 8 years of ownership and only because I felt it was time. No other reason. 

Can't speak to the other brands on the market.

Formula Cura. Not exactly budget, but easy to bleed and plenty of spares around if something breaks.

Otherwise Shimano Deore. Spares are a hack, but bleeding etc is pretty simple.
