Is it true the titanium one is more efficient?
See David Ure’s comments above.
How is the durability between the two?
Generally, Ti is more durable, HOWEVER the aluminum “flux ring” (heat exchanger) on the Ti version can be melted if you’re not careful. There have even been a few (three that I know of) reports of the heat exchanger melting when people were following the directions. See Titanium JetBoil Sol — Caution for details.
Any reason one might be easier to clean than the other? Or more resistive to scoring and scratching? I’m guessing the ti but don’t know if either or both have a finish on the inside.
Ti will be more resistive to scoring and scratching, Ti can also handle some fairly abrasive cleaning.
How about drinking from the mug? I’ve heard the ti is less likely to burn your lips but haven’t tried it myself.
Ti is less likely to burn your lips. However, if you use the supplied lid, the lid will protect your lips with either version.
Are both mugs the same shape? Does one pack more efficiently than the other?
The mugs are nearly identical except for materials. There’s no advantage to packability with one or the other.
And my last question is will the ti keep drinks warmer longer by any chance or does having the cozy on both render that an insignificant difference?
If the Ti version heats faster it will actually lose heat faster, but I think the difference due to the pot material is minimal. The user needs to make sure to keep the lid on and to cover the heat exchanger fins if he or she wants to retain heat.
Ti definitely costs more. Interesting to see the weight isn’t much different.
Ti as I recall is actually heavier for a given volume than aluminum. The “trick” with Ti is that it’s very strong so that you can make things constructed of Ti thinner. It is the thinness that provides the weight savings. In this case, though, there isn’t a great deal of weight savings, just slightly more than one ounce.
Thanks for the comparison and let us know some of the other pros/cons of one vs. the other
Right now, I don’t have access to the Ti version, and I’d be afraid to borrow one for testing because the heat exchanger can melt. Therefore, probably no comparison report forthcoming from me. :(
I have written a review of the aluminum version of the Jetboil Sol which should be published soon. I’ll post a link.
