1st set is usually so-so as I start with slightly less weight so I can make sure my form is in line. 2nd set is always the easiest and I add a few pounds while focusing on keeping good form. 3rd/4th (last) set is always difficult because my muscles tend to give out on me. If I can't finish my last set I'll drop weight and pump out the last few reps.
Have enjoyed this creatine addition because it's helped me have the extra oomph to power through those last few reps on the last set.
