I am a swisstool fan, but just on the tools themselves the tti is probably a better fit for me.
The Charge TTI does feel bulkier and heavier though.
I'm not saying the quality of the tools is better, just the options available. In my opinion the swisstool overall quality may be a bit better (aside from the phillips screwdriver) and offers better rust protection for those in wet/damp climates.
