I can safely say that only a few electronic instruments gave me tactile feedback similar to what I get from playing the guitar.
The Hammond B-3...considered by some, to be the first synthesizer...there was just something about the keybed, and the whirling set of tone-wheels that made you feel like it was alive under your fingers.
The Polymoog...not the most reliable synth, but it's touch sensitive keybed (a first for synths, as far as I know) was about the best synth action I've ever played, including any new ones.
The warm and rich sound from the analog oscillator's helped a lot as well.
The Fender Rhodes, and Wurlitzer electric pianos...not synths, but electromechanical instruments that rivaled the acoustic piano for tactile feedback and expressiveness of tone...they sounded at their best through a chorus pedal and a tube amplifier.
Roland Jupiter 8 (still have one)...offers an immediacy that still escapes today's synthesizers...the knobs and sliders make you feel directly connected to the sound, which, like the Polymoog, is analog and considerably impressive.
These instruments will always have a special place in my heart, because of the way they made me feel when playing them.
My little PSR-S910 is starting to get to that status...it just makes me want to sit and play....the SA voices like Sax, Concert Guitar, Jazz and Rock Rotary organs, really make me feel connected to the sounds....they respond naturally to technique.
