Perhaps, @lewm , but while we don't want to go down the headshell stability rabbithole here, I'd argue IF integrated headshells are generally equal or better than removable, it comes down to whether or not someone's personal best investment is in multiple carts or just one better one. If you have many mono LPs, and want to swap regularly a mono cart and a stereo cart...that makes sense. But many of us would benefit more getting the best cart we can and using it all the time.
Personally, I've had some fun doing quick swap shootouts with friends for sh*ts & giggles, but that's generally all it amounted to for me. Different horses...Cheers,
