BTW: looks like 5.2 is the latest untethered, 5.3 is available tethered.

Well I never really use the photo-stream or trailers so I'm hoping theres something else Im missing out on. What else are people putting on their jb'd boxes other than IceFilms, if thats even still around??
You can see all the updates between 4.4.4 and 5.2 here:
http://support.apple.com/kb/HT4448
In addition to photo streams and new trailers app, you also get support for bluetooth keyboard, iTunes in the Cloud, and some other minor features. If none of those sound interesting/useful to you, I suppose you need not bother. However, I'll note that the jailbreak process is about as easy as it has ever been nowadays: just run SeasonPass, run a little GUI on your mac to install XBMC and some other stuff (no command-line required!), and do some settings changes in XBMC. The macrumors thread linked in my previous comment provides step-by-step instructions.
I generally try to at least keep it updated to the most recent major untethered jailbreak version. One reason to do that is to avoid any homesharing hiccups between iTunes (which I am always keeping updated) and the Apple TV. (I have no evidence to suggest that having a much older Apple TV firmware working with the newest iTunes via homesharing would cause problems, but I hypothesize that if the versions get too far removed from one another there could be. *shrug*)
One issue you might run into: I updated my two ATV2's to 5.2 untethered back in February. Apple might not be signing firmware version 5.2 anymore. . . google around to see if someone else has successfully done it more recently.

Frankly it is getting less and less worthwhile to jailbreak as certain services become unusable. I never used Icefilms, but last I heard it was no longer working. (per this thread:
https://forums.macrumors.com/threads/1655211/ ). Also the Amazon Instant Streaming plugin for XBMC also stopped working earlier this year. People came up with a workaround so that XBMC would instead pop open a web browser, but that workaround only works on macs/pc's, not Apple TVs.
http://forum.xbmc.org/showthread.php?tid=108124&page=94 . Of course, nowadays you can just stream Amazon Instant Streaming to your iOS device and then airplay to your Apple TV, so this isn't too big a loss, but it's still one less reason to jailbreak.
The only plugins I've been using consistently have been Bluecop's Hulu plugin (mentioned earlier) and the "Free Cable" plugin. The latter just gives you access to those shows where the network posts a streaming version of their show on the network website. So, if CBS posts the most recent episode of "How I met your mother" on CBS.com to be viewed in browsers, that means the "Free Cable" plugin can stream that same episode directly via XBMC on your Apple TV.
With those two plugins, the jailbreak basically serves as a "backup" option for streaming shows that my EyeTV/Antenna system misses. If it's on Hulu or a network website, it's available to stream on my Apple TV. If you are interested in sports, there are some ESPN3 plugins that I'm told work pretty well, but I don't watch sports so I've never bothered trying those plugins.
I don't wanna deal with giant rabbit ears and fear signal quality with my proximity to the mountains....does anyone have experience with the newer box-shaped rabbit-ear-less antennas? My wife is really missing the damn Today show and doesn't want rabbit-ears either. I cut the cord about 3 years ago when Comcrap refused to keep giving me the promo rate they had for the previous 3... hate the thought of getting back in bed with the devil even if they will give it to me for the intro rate.
If you don't like the look of rabbit ears, you can get a flat indoor antenna. I used one of these (although the one I got didn't have an amplifier and was $20 at Home Depot). It worked ok but reception wasn't fantastic. But it's thin enough to fit behind the flatscreen so you can't see it.

Then I got one of these and mounted it in the attic:

Reception was significantly better, but the long cable-run to the TV reduced the signal power at the TV. So I got this amplifier:

Now the reception at my TV is fantastic. Been using it for several weeks and have not seen one single pixelation.
All this depends on your location/reception, of course. Plug your address in here and get an estimate of how good your reception will be.
