Yes, there is the point of 3dB drop, and there is the center frequency. These are not necessarily at the same point for the higher order filters. Therefore when combined you may get a hill or two. This makes it more complicated.
It appears unavoidable that each filter topology gives you an advantage somewhere, but then gives you a disadvantage elsewhere.
To get a seamless joining of the two bands, you can expect to do a lot of adjusting of gain, rolloff frequency, etc.... no matter which filter type you choose.
