That ported sub will be good to 22hz so you will definitely need a HPF (tune is about 25hz in 240ish litres). You will get a ton more output from the ported sub though, in the region of 6-8db more, while the sealed sub would go deeper. So you will be basically deciding if the sealed sub has enough output, and if not, then ported would be the way forward.
I would install the ported baffle first, and simply stuff the ports to seal it, re-eq, then see what you think of the differences. Its would be easier than swapping baffles, and if you can turn the HPF on and off, you would have a sub you can run sealed or ported.
Only thing I would say, is I would run with 3 of those ports rather than 4. It lowers the tune to about 22 hz, which still offers high spl output but offers slightly more extension while air velocity is still fine. The HPF could be lowered to 18hz then, but thats just my opinion.
