I also had the Alpine in my 2019 1500 and have the HK in my 2024, and I think the HK sounds better. I do recall back when I got it plenty of mixed reviews of the HK at the time, too. So maybe they'd made some changes over the years. I'd upgraded the dash speakers in my 1500 with the Infinity 3.5" speakers which were the go-to at the time and it did improve the sound, but I do think the HK in my 2024 sounds better.
I think in general it would also be helpful if people who don't like the sound of whatever system posted what their audio settings were (including whether or not surround is on, fade settings, etc) and what they're using for an input source.
Generally speaking, any terrestrial radio is going to be lowest, then satellite, wireless Carplay is next, then comes standard BT, then wired Carplay, and the best available to us would be a CD player (I bought a portable one off Amazon) plugged into the AUX input.
Here's a link to a comparison done in at least a moderately scientific method re wireless cp/bt/wired cp.
Also keep in mind lots of streaming services like Spotify allow you to separately change the quality during wifi use vs cellular use (and for downloaded songs too). I use 'Very high' (320kb/sec) for cellular and 'lossless' (FLAC). If you've never changed this, it's probably set in midrange quality as it's easier on Spotify's servers - if you have decent service, try upping the quality.
