In general, allow 4-5 watts per gallon of water (a full 20-gallon tank would need about a 100-watt heater, for example). I don't know about your second and third brands of heater. I have some Visitherm Stealths waiting to be tried out, others use them, though and can comment of their performance. In my 110-gallon stock tank, though, I'm using a Hydor 400-watt Thermo heater, and it's working well. I'm also using a Tronic and Ebo-jager in two other set-ups for a few years now, and they're also working well. You might want to check them out as well if they're available.
The XP3 is good value for the money, I'm using one and like it. If you have the tank full/nearly full, depending on what else you have in the tank, the size of your turtle, whether you feed in the tank, you might want to add a second, supplementary filter to help maintain water quality.
