I have used my spokeshave on oak, yew, maple and ipe. While i am no expert, I love using the spokeshave on oak and maple, however it chatters and tears out on ipe and on any yew that is not straight grained. I also find a sharp blade and proper tuning critical for most effective use. The spokeshave is a useful tool in my inventory, but it is only one tool. I have found it is important to find tools that work well with the wood you are using. Harder woods or woods with irregular or interlocking grain seem to tiller better when approached with rasps and files whereas softer or more straight-grained woods seem to tiller well with blades ( spokeshaves, drawknives, planes, etc.). Just my 2 cents.
