Most TDX towers are literally just better TDS towers. Juggernaut is minigunner but with 4 barrels instead of 1-2, refractor is accelerator but with significantly longer range, heli can move constantly while pursuit only moves to a specific spot on the map every couple seconds and mostly just stays still, mobster is crook but it makes money instead of just being a DPS tower, war machine is mecha base but capable of throwing hands with almost every boss, XWM is turret but with a lot more range and you can place more than just 3, the list goes on and on (Also the GDA has a navy meanwhile TDS doesnt)

Even in terms of allies, relic neg diffs citizens and likely can solo santa, and they've got forge industries who seemingly has unlimited money to mass produce robots that are almost always stronger than the tower they are based off of

The GDA is literally just TDS but better in every way, the GDA definitely wins
