Sequencers cover such a broad range of devices and modules. Some are very complex... which is good when you really have something complex in mind. But can be frustratingly tedious to program. So something simpler might be awesome to get immediate results from. But again, its simplicity means a lack of additional features. Neither is better or worse... just different. Sometimes you just need a hand-saw and sometimes you need an entire table-saw... to try and make an analogy out of it.
The biggest thing you'll want to worry about is getting your sequencers to play nicely with each other when sync'ing them together. Okay... here's where you get into trouble. One sequencer has to be the master that every other sequencer gets its timing from. They also have to have a way of starting together, so one sequencer has to send out a reset trigger to every other sequencer when play starts or your sequencers might be out of sync and not playing when you'd like them to. Another issue is HOW your sequencer interprets clocks (timing triggers). A trigger is a short square wave. Some sequencers use the leading edge of the square for timing, some use the falling edge. This can be problematic and lead to issues, especially concerning triggers that initiate the reset. So before bringing a new sequencer home... you might want to make sure it'll play well with everyone else or at least buy from some place with an easy return policy.
