That depends somewhat on where you are and what your priorities are. I'd agree a 165x is better for almost every feature.
The 1630x is more for nostalgia and maybe very low price. I do think it's manuals and usage are better than later models if you're learning.
The 16500/16700 are very fine .. if you can stand the fan noise and bulk (or change the fans). If you want the light weight etc, of the 165x,. what's the best option ? The later integrated units are still quite large.

Not sure if that is still the case with the more modern Tektronix TLA700/TLA7000 series. One feature the Tektronix acquisition modules have is a 56 bit timestamp for each samplepoint. And this timestamp does not eat into the acquisition depth like the HP / Agilent logic analysers do. The timestamped recording is a very nice feature to reach long records (in time) without needing hundreds of megapoints of memory.

When timestamping is selected, the HP/Agilent analyzers actually provide a choice of either halving the sample depth, or you can leave a pod unassigned and still get the full memory depth (at least on the 40-pin 167xx modules). It's nice that Tektronix designed in a consistent timestamp without any tradeoff complexities.

I'd say the 1630-series is only for nostalgia. Unless you can find one for local pickup, with shipping factored in you probably won't save much compared to a significantly more capable but still portable 1670-series, with the best choice being the 1670G series with color LCD, which saves on the weight of the CRT, which might be dim and suffer from burn-in.
I do have some 1630-series myself, strictly for nostalgia purposes. The have noisy/bouncy front panel buttons, very limited capture depth, somewhat narrow screens which may cause the need for more horizontal scrolling, no built-in storage which requires the addition of an HP-IB floppy drive or HP-IB floppy drive emulator (HPDrive), no network connectivity, limited Inverse Assembler support compared to all of the newer series, clunkier probes, etc., etc.
