Phil made a good point that I would like to expand on. Any router that must be turned in the base to make height adjustments is easier to work with using a router lift. Why? First would be the fact that with a router lift your switch is always in the same position. This ends fumbling under the table to find where the switch is. Adjustments are faster using a lift, especially on large changes.
For many years I have said that lifts are great for people with physical limitations; and for those who simply want one that's OK too.
None of the under the table adjusters or lifts are as fast as popping your router out of the table to make changes. Some people prefer them and that is fine; the goal is to be as comfortable as possible with your choices in how you use a router.
The Bosch 1619EVS (GOF 2000 ACE the other side of the Atlantic) is the only router with a spring defeat feature as shown in the photo. This is very handy for people who use their router in a table and free hand. This is the only plunge router Bosch recommends for table use.
Other plunge routers used under the table are easiest to work with when installed on a mounting plate and with the springs removed. They allow for the fastest bit changes and height adjustments when popped out of the table. (Using wrenches)
About 10 years ago the quick change collet was born. John DeRosa invented The Eliminator chuck. Soon after the Extreme Xtension was cloned from it. Faster than factory collets but with the disadvantage of marking up the bits shanks; also prone to increased vibration. John next invented the Musclechuck. This is as good as it gets for quickly changing bits but it has one limitation: on some routers that do not have enough travel you can not make cuts shallower than 3/16 of an inch. This is because the Musclechuck extends the bits mounting position by about 1/2". This is when using normal length bits; using shorter bits solves the problem. The additional 1/2" cutting depth can make the difference in completing a cut without an extension so it is a worthwhile trade off. After all, how often do you make dado cuts less than 1/4"? The cost of an extra bit or two for these situations becomes irrelevant.
