Adding this answer because I felt obligated to correct a few things the other answers say.

Both moves are bad because offensive Swampert is bad.

I wouldn’t call offensive Swampert bad. Choice Band Swampert actually has a niche in UU. I asked on Smogon what CB Swampert does over physically offensive Water-types like Gyarados, and this was the response:

CB Swampert has a few things going for it;- secondary stab that 2HKOes Amoonguss & Slowking / OHKOes (or comes close to it) some other Water resists (Keldeo, some Primarina, Tentacruel) which makes its switchin pool limited and kinda weird- Ice Punch lets it nuke Salamence which is pretty notable among physical Water types- Ground typing lets it block Volt Switch and means it’s not scared out by some things other Water breakers would be forced to switch by (Raikou, Rotom-H for instance)- flip turn hits pretty hardthe tier just doesn’t have a whole lot of water types that can go physical so pert is unique in that sense, it’s just generally very prediction heavy and the reward often isn’t great if you run into something like a rotom or tangrowth. fun af to use if you really wanna try it though

As for whether Liquidation or Waterfall is better, Liquidation is better, but not because of the Defense drop. Liquidation is used since it has more power than Waterfall, albeit by a 5 BP difference. Liquidation is mainly for the 2HKO on Hippowdon. Also, Swampert’sAnalysis Pagelists Liquidation as the powerful Water STAB for a Choice Band Swampert set.

TL;DRLiquidation is better on Choice Band Swampert as it has more power, is used mainly to 2HKO Hippowdon, and offensive Swampert has a niche over physically offensive Water-types like Gyarados due to its Ground typing and being able to pivot with Flip Turn.

Liquidation is the better option, here’s why

Swampert has mediocre speed meaning it wont be able to flinch most opponents with Waterfall due to flinches being based on speed however Liquidation has that 20% of lowering the opponent defence and can be useful when weakening the opponent to deal more damage.

Hopefully, this helps :)

Both moves are bad because offensive Swampert is bad.

Swampert has neither high speed nor aqua jet. Its physical attack boosting moves boost it by only one stage, and they don’t also boost speed (technically except ancient power, but that’s unreliable). Swampert’s damage boosting ability is risky and difficult to activate. Use Gyarados or Crawdaunt if you want a physically offensive water.sourcesourcesource
