Those two choices aren't showing in the post, so I can't pick between the exact models. For a basement grow space I'd care less about the brand name and more about whether it can drain continuously to a floor drain or sump, restart after a power blip, and actually pull water at cooler basement temps.

If you're smelling must and seeing mold spots after rain, size it bigger than the room chart says. A 50 pint/day unit is about the smallest I'd look at for a damp basement with plants, and if it's a larger basement or you've got a tent full of plants transpiring, I'd rather have the bigger unit cycling less than a small one running flat out all day. Bucket-only sounds fine until you miss one emptying and the RH climbs right back up.

For the grow, I usually like the dehu in the lung room/basement air instead of crammed in the tent, unless the tent is sealed. Let the exhaust and air movement mix that dried air through the space. Also check gutters, grading, seepage, and any bare concrete/crawlspace moisture source, because a dehu controls the air but it won't fix water getting into the structure.
