You have to judge for yourself what will be too little, too much, or just right for your first build. In general, I would agree that starting with a simpler kit is a good idea. I think a lot of people take on a project that is beyond their ability or turns out to be more effort than they want to put in and end up getting burned out before they finish and go back to ARFs. If you go with something simpler, you can get through the build with a sense of accomplishment and a fun to fly plane. Even if it turns out that it was too easy, after a successful build, you will be far more likely to take on another project than if your first build turned out to be too hard.
Having said that, I started off with a TopFlite Spitfire as my first build. I did start and finish a 4 * before completing the spit, but in the long run, I was able to work through it and end up with a plane I'm happy with.
