Have and have shot both. LS-P has a longer sight radius, arguably a better trigger, costs more, and has a smaller grip. The Lim Pro grip is bigger, and fits my hand better. The trigger needs more work to be 'good enough'. The chrome finish on the lim pro is better - the upper on the LS-P is blued, and that bluing rubs off easier than the polycoat on the SP01 lower. Lim pro mag opening is bigger and easier to hit than the smaller SP01 opening. Better is relative. I had been preferring the lim pro, but recently liking the ls-p.
