It is very different point grid.
Wyndham RCI/II generic deposit grid is start from 28k Stdio blue season, 42k stdio white season, 70k Stdio red season, 105k 1BD red sason, and so on.
WM RCI/II deposit is start from 4000 Stdio blue, 6000 Stdio White, 8000 Stdio Red, 9000 1 BD red.
So it all depends on what kind of depeosit you need to put in.
Generally speaking, WM's prime season, unit size does not cost too much more than a bad season, small unit. Wyndham you will see the difference close to 30% various with area. And with new introduced president suit, it will cost over 50% in some cases with just one unit size upgrade. or 300% compare prime season to bad season.
So, if you always want to travel with 2 BD unit prime season in mind, WM will be much cost effective.
