If you are learning about timing and phrasing a metronome can be a really useful tool. It just depends on how disciplined you want to be in your practise and what you want to achieve. I've never felt that playing with a metronome detracted from any feel. Quite the contrary I feel. The job of the rhythm section is to keep it tight, but that doesn't mean that it has to be uninteresting. Groove is something that is fluid, and the loosest sounding of grooves are actually incredibly tight, but they know what to do with the phrasing. Unless you understand timing then that's not possible.
