Are Tracer MPPT controllers (2215RN) actually better than PWM?

[Wakie]

I own a tracer 2210 rn

It is a mppt, i use it with two 230 w grid tied panel in serie .
It transform the 70 volt into 28.8 v to charge my 200 ah battery (24 volt)
It as temperature compensation, you have to mount it close to the battery.
Never have a problem in two year

Just checking to see if anybody had used one of the Tracer MPPT controllers, I was looking at the 2215RN 20a 12/24v for under $100, but do not need to spend the money if they are not an actual MPPT with real gains over a PWM (I currently have a renogy 30a). I am familiar with the differences between MPPT technology and PWM, just wondering if the Tracers were real MPPT, and If anybody had any experience with them (good or bad).
thanks

It is an MPPT controller, that doesn't necessarily mean it's a good choice. What do you have for a system?
