single deck vs multi deck blackjack, which is better odds?

so, i’ve always heard single deck blackjack gives you way better odds than multi-deck, but lately i’ve seen some tables where the rules on the single deck are pretty rough, like 6-to-5 blackjack payouts or dealer hits soft 17. meanwhile, the multi-deck games let you double after split and pay 3-to-2. makes me wonder if the deck count really matters as much anymore, or if it's all about the specific rules they toss on each table.

i get that card counting gets easier with fewer decks, but i’m not really counting when i’m just passing time at a table, so i’m trying to figure out what i should prioritize. the vibe is always different live anyway, especially if you play with the same dealers for a while. looking to see if anyone else steps back and just focuses on the rules over the number of decks.
