Combine a cartridge filter with an oil extractor and you don't have to get under the car to change the oil! I've done oil changes on my TDIs this way - it's fantastic and actually removes more oil than a bottomside drain (when you suction out the oil cooler at the filter housing base).
I also like that with cartridge filters the oil bypass is built into the block somewhere - no more worries about bypass valve types or what material it's made of. Another a big plus for the BITOG crowd is you always get the chance to easily inspect the filter element instead of having to cut open the can of a spin-on filter.

I replaced the o-ring, but forgot to oil the new one and the threads on the plastic housing, until I finished pouring the sump. No biggie, I'll keep an eye on it.
I'd rate is just a tad more tideous than the cannister style, but just different. Something I'll get accustomed to after a few oil changes.
In terms of functionality, I see no difference. My only discern is that the OEM Toyota had the cheaper "glued" end but any OCI less than 10,000, I don't see a problem arising.
I agree with above. Changing cartridge filter is more tideous than the canister style, especially when you need to change 4 o-rings on the filter holder.
One big advantage is you can inspect the filter element at anytime you want, if it is mounted on top of the engine. Once in a while, when I was so bored, I removed the filter holder in the evening to take a peek at the filter media then re-installed. If you do that with canister filter, you can not see anything other than inlet/outlet holes.
