PP - basicly fullbuff, missing only vampiric which you could buy for fishes (around 15k adena - if you are to lazy to fish - which is nothing)
SE - missing haste, zerk, gr. might, m.barrier.... m.barrier obtainable by fishes again, haste from clan hall (5500 adena or sth)... so only handicap is g.might, zerk... BUT it has recharge (till lvl 76 you can easily solo AOE with se/tyr duo) and has stigma... stigma is OP for 1v1 (you can make loop macro to use it so basicly no need to alt-tab between each mob)...also if you will go to loa for example purify is another BIG advantage + easier to find pt if you have own recharge box (mostly welcomed in EV and ABG)
with PP your optimal journey through server would be +- like 40-59 FOM, 60-67 SOS, 68-xx BS/SV/FP
with SE you can go wherever you want.. in tough locations (dv, loa, sv, toi...) do 1v1, in easy locations solo aoe (aligator, above IT carter, ev, FP...)
Current meta and "best" and most recomended setup is probably PP tho, but in my personal opinion duo with SE is more versatile...also with stigma you wont feel much difference between dps despite lack of zerk/g.might
w/e you chose its only up to your personal preferences in the end, but if i had to chose i pick SE all the way, simply not to die out of boredom
/edit: if you plan to aoe DONT level up your aoe skills too high, i think their dmg depends mostly on your p.atk, not the power of skill itself, so better is to go + str dyes and you will save lot of MP cos of that)
