I never used both of them, but from what I've read so far from here and other forums, the Trustfire is a much better battery. If I'm not mistaken, they are made from the same company but the Ultrafire's, in my opinion, looks more on the cheap end. I only use AW IMR batts for my mods, so maybe someone else that have used both can clarify.
IDK, which do you like, Duracell or Eveready? Trustfire and Ultrafire are both Li Ion batteries, there are also AW Li Ion batteries, and several others. How much actual testing/grading actually goes on compared to just marketing hype is really just a guess, I doubt that there is a person here that has ever been to those plants to see for themselves.
I've used Ultrafires, Trustfires, and AW's in my mods. The AW IMR's are the only ones I buy anymore. One set of UF's wouldn't fire in my vv mod but worked in other mods. The TF flames worked ok and lasted a long time. But the AW's have a higher discharge rate so I get better hits with them, and they last quite a while too. My suggestion is to spend the extra couple of bux and get the AW's.
Neither. The Panasonic CGR18650CH is currently the best 18650.
Has Safe chemistry, 2250mah., outperforms AW IMRs. in drain testing., outperforms AW IMRs in forced failure tests (Panasconic 185 degrees, AW 235 degrees) Same 10A discharge rating as AW IMR. It costs more than **Fires but less than AWs. ($7.99 at Smartvapes and $10 shipped at orbtronic.com, also at CalliesKustoms). Less counterfeiting risk than AW.

Unreliable 18650 batteries like xxxfire, are generally not recommended.
Sailorman has discovered this battery (CGR18650CH), and according all test results it seems that this is the winner (price,performance).
Maybe the most important thing is that it is coming from Panasonic, so you know what is inside, and how it will react in case of accidental short.

BTW, the 3100mah 18650 at Callies', in Strontum's link is also an excellent battey. It's not an IMR, but it's an excellent Li-Ion and I believe it too is available at Orbtronics and Smartvapes. Either one of these is far better than any of the **Fire batteries and even superior to the nearest AW battery of it's type.
Glad I found this thread! I've been looking at the CGR18650CH at smartvapes for a while. Thanks sailorman for confirming that it is a great battery.
I have a few questions though... First, is it actually an imr? Second, does imr always mean li-mn? Third, how is it's chemistry different than the 3100mah batt in strontium's link? Or are they the same chemistry but the 3100mah also has a protection pcb?
And finally, is this an imr, or an unprotected regular li-ion? LG Lithium 18650 Cylindrical Rechargeable Cell: 3.7V 2600mAh (9.62Wh))
Sorry for all the questions... But I know this stuff really matters.

The GCR18650CH is actually a hybrid battery. I refer to it as an IMR for sake of simplicity and so I dont have to go into long explanations. There are links to the Panasonic Data sheet on the "Slayer" thread that go into greater detail. Panasonic uses a formula of manganese and cobalt in this battery. It's a "modified" IMR and preserves the inherent safety of a "purebred" IMR. So, technically, it's not an IMR because IMR designates a battery with strictly Lithium-Manganese chemistry.
It's chemistry is different than the 3100mah in Strontium's link. The 3100 is a conventional Lithium-ion chemistry with a protection method that is not the PCB like you find in the Ultra/Trusfire batteries. There are also links to it's datasheet on the "Slayer" thread. It is a protected battery, but doesn't use a PCB for that protection. In that regard, I consider it safer. The Panasonic device should prove more reliable than a PCB, which can easily fail, especially on a cheap Ultra/Trustfire. The Panasonic 3100 also contains other protections against thermal runaway, as demonstrated on the video posted in the "Slayer" thread.

Also, the LG 18650 you linked to is NOT a protected battery, as indicated by this bullet point in the listing.
A protected battery will contain that IC within the battery body.
It also has a 1.5C, or 3.5 amp maximimum discharge rate. The Panasonic and AW IMR batteries have a 10 Amp discharge rate and the 3100mah Panasonic has an 8.5 Amp discharge rate. The LG has a discharge rate about on par with the Ultra/Trustfire batteries.
