I've owned the FT-990 since buying it new in 1997. It has all the filters and the TCXO. NEVER any problems, ever. I use it regularly for contesting (CW, SSB, RTTY) and rag chewing. The internal antenna tuner works very well as you may recall. Also, a plus, any filter can be selected in any mode. So, when operating any of the digital modes in AFSK, you can even switch in the 250 Hz filter. Can't do that on the 940. Granted the 940 has a few more bells and whistles that all work, it has those through-hole soldering issues that may crop up and need fixing. It's a toss up though. I can attest to the 100% reliability, at least so far!
