+ 1 for the M9. I have used boutique pedals for years (mainly EBS) and swapped to M9 last year. True bypass and so easy to operate. I didn't want amp modelling - the M9 is just stompbox modelling. As Johnthebassist says, distortion is not great, but I use drive on my pre-amp for this anyway. Pitch and filters and octave are very good.
