Bosch Cordless vs Corded Hammer Drill

I own both models of bosch drill, one is corded and another one is cordless.
Here are the summaries and differences between these tools.
1) The corded drill has only 2 modes (Drill and Hammer) while the cordless model comes with 4 modes
2) It is more convenient to use the 18V cordless bosch hammer drill model while the corded model last longer for heavy tasks
3) The design of the forward/reverse button is different
4) The cordless model use SDS drill bit which is easy to be changed while the corded model use "old style" adapter and chuck. You would need the key to loosen and tighten the drill bit.
5) Drilling Performance - Both works great on drilling the concrete
