Trampoline v climbing frame?

[TwinklyLightsForXmas]

We're thinking about getting DS one for his birthday . We don't have space or budget for both. Which would we get more use/enjoyment from? He'll be 5 in November. Thanks!

Had both, and swings and slide and tree house/fort. Trampoline by far the most used, all the others fell by the wayside and dismantled except the trampoline and mine are now 14 and 15 and they still use it with their friends. Do get it either sunk or with a net though!
