The dunlop will be more reliable but the EB is SMOOTH and the taper is great. What's important to you? The feel of the pedal or if it works or not? There are tons of volume pedals but there's a reason th EB pedal is the standard.
I'm using the EB VP jr. Very smooth, quite and I also like that it's passive. It's essentially another volume control for your guitar and acts in much the same manner.
Boss is another very good pedal and used by many of the pros.
