Solar charger - tempature compensation really needed?

[marty9876]

I'm building out a 200w solar setup (might expand to 300w) and I'm stuck on controller selection. MPPT seems to be a given, I want to stick with the popular brands. While I read tempature compensation has its value, I'm just trying to determine how much value it really is. At this size of controller, only one of the controllers actually comes with the remote tempature sensor the rest is an add on which leads me to think it might not be too important.

Basically, is it worth $150-$200 to add tempature compensation?

I'm trying to get myself settled on a Victron BlueSolar 75/15 MPPT (I know it would only do 200w and has ambient air tempature compensation- not on battery). With the blue tooth dongle it's $150, compared to a Morningstar for $300-$350.

Looking at Victron, Morningstar, Blue Sky, Midnite, Outback, Western.
