10-hole diatonic vs Chromatic harmonica

A diatonic is tuned to one key and bends notes; a chromatic has a slide that gives every note in any key. They are different instruments, not better and worse versions.

Side by side

What it is
10-hole diatonic harmonica: Ten holes, twenty reeds, tuned to one key. The harmonica of blues, folk, rock and country, and the one almost every beginner starts on.
chromatic harmonica: A slide button raises each note a half step, so one harmonica plays every note in any key. Usually 12 or 16 holes.

Questions

Should a beginner start with a diatonic or a chromatic harmonica?
Most start with a 10-hole diatonic in C: it costs less, most lessons use it, and every tab on HarmoniTabs is written for it.
Can I play your tabs on a chromatic harmonica?
Not hole for hole. Our tabs are written for 10-hole diatonic harmonicas; a chromatic has a different layout.
