S24+ to OP13

I'm debating whether to exchange my s24+ exynos for OP13 (I could sell s24 used and use the money to buy second hand OP13 for not much more). I'm mainly tempted by battery life and have been curious about how OP is this days - my last was OP6T and was happy with it, until they merged with Oppo and went downhill with quality and speed of updates.

The main concern for me are the speakers - I've read opinions they are bad. So question for anyone that has the comparison - how do they compare to s24+? I find those not that great and would not want to change to even worse. Any other potential downgrades I should be aware of?
