Personal opinion: Beatpad 2. Why? I just can’t get around the unconventional button lay-out on the Wego.
Also I think the BP2 has the more mature set of features. Not in the least the more or less standard for controllers these days of 8 performance pads per deck, but also the jogs.
Finally I am not to crazy about the Pioneer sound on the high end models and I don’t think it gets any better down the model range.
As is always the case, it’s a matter of budget, desired features and personal preference.
So, just my three cents worth.
