Compared to the arcade version (which you can get on PSX and Dreamcast these days thanks to Hasbro!), the 5200 version only has a few minor differences in gameplay. First of all, only one Ugg and one Wrongway will appear in 5200 Q*bert, as opposed to multiples in the original coin-op.Some of the Disk placement is a bit different at times, and Coily's tendencies are different (for example, in the coin-op version, he tended to take the upper route to get to you, but seems to take the lower route more in 5200 Q*bert). Not to get anal-retentive here, but I thought it was worth mentioning!
