We use xtramath.org, cardstock flashcards and a brilliant little handheld thing called a Flashmaster for all math facts practise. For us it didn’t matter whether it MUS or TT…my kids still needed to put in the time to memorize their multiplication tables and all the facts.
FWIW, I have viewed the lectures on multiplication from BOTH MUS and TT. In terms of presenting what multiplication really means and how to understand it conceptually…the two programs and their respective ways of presenting made little difference to my boys. I have one boy who found the MUS presentation quite muddled, but he still got the idea behind multiplication. My other DS saw only the TT lecture on conceptual understanding of multiplication and he got the without problem. The initial conceptual understanding made no difference in the end though; what HAD to happen for six months afterwards was daily drill to memorize. So that’s what we did (and still do!)
The only other point that might be worth knowing is the fact that in TT, after the initial lecture on conceptual understanding you go through a new multiplication table EACH day/lecture. So if you are doing math every day, your kid is getting the ENTIRE set of tables in about a 2 week period. They spiral through all previously “learned” facts daily (I say “learned” because clearly it wouldn’t yet be memorized) but certainly, without extra practise I think it would take a VERY mathy kid to get all the multiplication facts memorized with only the TT material. And yes, I do think that TT could do a favour to parents and point this out so that parents are prepared and know that they should schedule in extra drill time.
The fact that TT requires the extra drill didn’t seem a fussy point to me in the least – again, because my kids also needed tons of extra drill, worksheets, flashcards etc when they were on MUS. We finished Alpha, then Beta, and still had very few of the facts truly (instant recall) memorized. Maybe that’s just us, though.
HTH! The good news is that with xtramath.org (which is free), other free online resources and the simple use of flashcards every day, this situation is pretty easily to deal with.

PS – like crazy4boys above, we took a pause (2-3 weeks maybe?) in doing TT daily during the time we were first working to memorize x/facts. After the initial multiplication memorizing “blitz” we went back to daily TT and doing drills on xtramath and via flashcards every 2nd day or so.
