Pit's arrows are infinitely better then DP's. Even DP with the guiding bow custom is still worse, since they're too slow to catch people off guard or even hit people offstage as effectively. Like I was saying, it doesn't mean much of anything in some matchups, but against most it's huge.Pit is not clearly the better of the two.
Electroshock VS Upperdash is more of a draw. Some characters are more easily handled above you, some offstage, Elec kills earlier, Upper kills consistently, Elec can gimp, and Upper can be followed by an arrow. Things become less even when you take into account platforms, where Upper KOs much quicker.
And unless you wanna factor in Final Smashes, the only remaining difference is Ftilt. Pit's KOs at tippered 170% in training, center-stage. DP's is 210+ or so. Untippered Pit's is still better, since there's still too much KB to combo from even with DP's weaker KB. DP has absolutely no advantages to make up for this.
I mean, it's mostly preference for any given matchup, but Pit is just better for most. DP does, however, have better matchups with Mac and Rosalina.
