Interestingly, that's what people say about Timba who don't understand it.
As someone who loves all kind of Salsa music, including Timba, I think you're approaching this kind of Salsa from the wrong perspective. You're approaching it from a direct comparison with Timba and finding it lacking in thick layers of complex rhythms (that wall of sound some people who don't like Timba complain about) and the same kind of variations (gears) that you like in Timba. Timba's structure is quite different from Salsa.
Instead try to find a (non-Timba) Salsa track you like and focus on the positives. The aspects you like about it, whether it's the piano riff, the melody, a nice bit of Conga or whatever. Tracks you like tend to grow on you with time.
I would suggest listening to Colombian salsa, as that has the same structure as NY/PR salsa but often with a more heavy use of conga similar to Timba. Back in 2003 Colombian salsa was my bridge from NY/PR salsa to Timba.
You may dislike bananas because you don't like the taste but It's crazy to dislike bananas for not being an orange. Both fruit are nice in their own way, although I prefer Bananas. Gaining a taste for something new takes time and happens little by little as you listen to new tracks.
Helps if you also don't picture yourself dancing Casino to it as it won't fit right. Find some video of cross-body dancers you like who are musical and learn the music through them. Dancing and music go hand in hand.
Also sounds like the selection of Timba you like is also fairly limited at the moment. Expanding horizons is good whatever style you like. Have you tried Suave Tumbao, Calle Real, Havana D'Primera and NG La Banda?
