I've got the TG3 with MX Clear switches. Very nice key feel, a little tactile bump, but stronger than MX Browns. Highly recommended, if you like MX White or MX Green switches.
If your preferences run towards MX Red or Blue keyboards, I would steer clear of MX Whites, they will give your fingers a work-out!
One note about the TG3; it uses a non-standard key layout, seems to be optimized for no stabilizers (only the space bar has one). This means the "1 !" key is almost 1.5x, Enter key is the same size, etc. All the same profile, like tall DSA profile? Also the LED backlighting on these keyboards is 12v, which requires some fairly extensive modding to make work.
Give your interesting collection of keycaps

I would suggest you get the Ducky keyboard for ease of swapping. The TG3 is very well-made, but I would think it's more for fans of industrial chic.
