I would say it depends on how often you use the knife blade. The TTi has an S30V knife blade, which is the only reason I'd spend the extra money, but which I doubt I ever will because I don't use the knife blade on my Wave or Juice (S2 and Xe6) hardly at all. I always have a "real" knife on me, and most of the time it is an S30V blade (Bradley Alias I), but even when it ain't that one, it's still better steel than the 420HC of the Wave or all of the Juices.
If weight is the major consideration, the TTi does provide a little advantage, as it has 19 tools and 8 bits coming in at 8.2 oz., while the Wave comes in at 8.5 oz. with 17 tools and only 2 bits.
The Charge AL is likewise 17 tools, but with 8 bits, at 8.3 oz., and the ALX is 18 tools/9 bits at 8.3 oz. also, but on both the AL and ALX, the main knife blade is 154CM steel, a great, durable steel for knives, and the extra 1/10th of an ounce hardly seems to justify an extra $100 bucks even considering the higher-end steel on the TTi.
In short, no, it ain't anywhere near worth the extra benjamin, although to be fair, there are several places to find the TTi that the price is nowhere near as much as $100 bucks more than a Wave. Still ain't worth it to me though.
