Default 4 stroke vs two stroke

I've never used a 4 stroke engine on a bike but I just built my third two stroke model,it ran like it was broke in and balanced on the first run.the last one is still breaking in after a month .If anyone has built some 4 strokers as well as two how do they compare pros and cons.
