Should I use Slaking or Regigigas against my friends in Black 2?

So slaking its the best no legendary Pokemon and regigigas well one of the best legendaries but the two have horrible abilities regigigas halving his stats until 5 turns and slaking not attacking every 1 turn I am creating a team to battle my friends in black 2 and since they are going complex for some simple battles me too so yeah who do I put on my team?

I would say pick regigigas because his STATS are better than slaking’s STATS and regigigas has pretty strong moves like focus blast,,thunder bolt,,hyper beam,,stoneedge and earth quake so pick regigigas

Slaking by a mile

They both have trash abilities, but Regigigas is worse.IT RESTARTS SLOW START WHEN SWITCHING INand if you survive slowstart somehow, no healing while slaking gets Slack off

Slaking can be on the field for 3 160 attacking moves while regigigas has 5 trash turns

as demon flygawne said, Giga impact fits slakings ability while slow start cant be that good.

skill swap/gastro acid is very situational and these 2 deserve to be in the tier they are in
