I have not used the ultra sol.
I have just used apx. 3 gallons of the med. poura sol
as a whole it was very good,
did have some micro bubbles.. more bubbles with smaller batches like 4 oz..
with 16 oz batches the bubbles were way less..
does smoke a bit too..
the settling was very little and could be shook up very easily
the baits are a touch tacky too seems to go away after a couple days..
all of my pouring so far was with salt & softner added.
I have only poured calhons,, Lure Craft & the spike so I can not compare to any others..
can not beat it for the price..
