I have used a Charge TTi for about 4+ years. It has been through 9 regionals and 4 CMPs with me...along with uncountable hours in the shop and at home... The blade is very sharp and very good steel better than any other knife I have. (154CM)
It is really nice that you can open the blades without opening the tool
I have used the huge variety of bits on many occasions.
I would recommend that you purchase the bit driver extender

... this fits into the bit slot and allows the use of regular 1/4" bits of any sort... or even a nut driver with a quarter inch base. You could probably even use it with some type of quarter inch adapter for sockets.
I also use a leatherman case

The premium nylon one... It has 3 tool slots and the bit extender and a group of 1/4 bits fit in to two of them and a mini-mag lite fits in the other.
All in one kit...
The Charge is a lot of tool... fairly heavy compared to the Gerber.
The Gerber is nice though... and certainly less expensive.
I have used probably 8-10 different multitools and the Charge is the most versatile and useful I have come across.
I have the Charge TTi... but the newer Charge ALX and AL certainly look nice.
Same features...pretty much...
The only thing I don't like about the TTi is the crimper cut into the pliers.. It makes the plier jaws pretty small. But I have never really had any problems
My suggestion is for you to go out and hold these in your hand and see what you think is better. Talk to some other people that use them and see what they think.
Leatherman has been around for a long time... I even have one of their original tools.... They have learned alot...
good luck!!
