I fly both and both have pro and cons. WHEELS : Funny to taxiing on wheels...and landing only nose wheels in mountain side
More easy to land on sea carrier in bad wheather (small or Xsmall , big one same same..) Easy to autorotation on hard runway.. on smooth surface looke like sand, better skids....
Maintenance and weights...Cheaper on skids and you can't miss to low gear...lol
