Which is better for a first bass setup?

The TROPO-1X12D2. It comes assembled, wired to 1 ohm and tuned to 34 Hz, so you only need a 1-ohm stable amp and one wire run. The bare TROPO-12 still needs a box and coil wiring.

Is the loaded box worth $90 more?

Yes if you would otherwise buy or build a ported box. A comparable kerf-ported MDF enclosure plus wiring and hardware usually costs more than $90. Skip it if you already own a box.

The TROPO-1X12D2, on paper. Its box is tuned to 34 Hz with 2.13 ft3 of volume. Buyers of the bare TROPO-12 say it is strongest between 30 and 40 Hz, so a custom ported box is needed to match it.

What amp do I need for each?

Both handle 650W RMS. The TROPO-12 wants an amp that makes 650W at 2 ohms. The TROPO-1X12D2 presents 1 ohm, so it needs an amp rated 650W at 1 ohm and stable there.

Neither has a clear edge. Both use the same TROPO-12 motor and 2.5-inch copper voice coil. The loaded box protects the sub better with an air-tight flush mount, but the sub itself is the same design.

Can I move the loaded box's sub to another enclosure?

Yes. It is a TROPO-12 dual 2-ohm sub, so you can pull it and rewire it to 1 or 4 ohms in a different box. You lose the matched kerf port tuning if you do.
