Its honestly up to you. I have a manual as they work fine and are way cheaper.
Plus I keep my boost on my Mazda at a daily set 20-21psi.

As said above, electronics are good for daily and race boost. I dont believe and daily and race boost. You either boost or dont.

Whats good about most electronic boost controls is that they have more than boost settings. You can set boost spikes, create boost creeps, reduce or add turbo lag, and other crap.

Also, to reduce creep and spikes with a manual boost controller use short lines. And DO NOT use those colored silicon lines. They expand with heat causing over boosting.
