@CAVOK2012.
You refer to "the C152" (singular) at the other place, and "the Tecnams" (plural) at the current place. Perhaps aircraft availability might be better where you are? 50H checks, tech issues, other calls on that single aircraft mean you are fighting more than the weather while trying to stay current.
Similarly, when comparing places, how much of the flying time will be spent going to/from a training area, stuck at the hold, etc? Will the airfield be shut for most of the winter?
Less currency means more hours to PPL, ie extra cost. In my limited experience of PPL costs, the cost per hour has a smaller impact than total hours flown*.

*You could argue that those extra hours are not ultimately wasted, but I suspect few PPL students put much faith in that!
