for newb yes... pa is easy to use and good. for those in the rank of maybe 3.5k mmr above, pa is kinda weak... too easy to counter, nuke supports + mkb oriented carry will melt u. there is no 'most powerful', there are only popular heroes in current patch.... example, ember used to be physical build in previous year... but now, u will see magical build ember.... there are 'easy' to use and master heroes, pa is one of it. try using pa mid vs a good meepo mid.... i dun wanna fight into that.
