I am switching to syn (probably Ultra or M1 EP) and want a filter that can last for an extended drain. Advice, observations, what do y'all think?
There really is no way to compare them without laboratory style testing or a number of field tests.
Increased capacity is not going to show up a difference in normal usage, say twice a year filter changes with typical driving.
Years ago when Champion was making both the Mobil 1 and the Delco Ultraguard I had the opportunity to compare them in some extended testing. The longer you ran them the better the Ultraguard looked.
But in the long run, given the high cost, the Ultraguard went off the market.
With some niche exceptions that has been the case with high capacity filters - usually with some synthetic media - like the Hard Driver, the Ultraguard, and so on.
If they filter at the same level, you can buy two or three normal capacity filters for the price of one high capacity filter, and just change them more often.
As far construction goes, the PureOne and the Bosch Distance Plus appear to be - except for the media - the same filter.
