Could it be that it's a US-specific thing? My last three phones have been EU-sold Samsung S series, and the only things I'd consider "third party bloat" were pre-installed versions of Facebook and MS Office, both easily removable.

The Samsung replacement apps is down to personal preference, I find them easier to use than Google "originals".

Having casually interacted with phones from other brands, I consider Samsung among the best Android options as far as software and UX goes.
