Depends on what you're after. If you're into visual and want the biggest scope you can afford/handle, go for the dob and learn to track manually. Eventually it'll be second nature, like driving a manual car
. You'll want smooth motions, as a jerky dob will create mass quantities of frustration. Not sure how the SW dobs fare in this department. You could get an EQ platform, but these are fairly pricey.
An EQ mount will provide easier tracking, but take more time and effort to set up properly (bigger learning curve aswell!). But take note, that a Newt on an EQ mount will result in awkward eyepiece positions which will require rotating the tube to get the EP in an ergonomically comfortable postition as you swing it across the sky. EQ mounted Newts are generally not recommended for visual for this reason, but you can get a set of rotating rings which will allow you to rotate the tube within its cradle.
I'd say try before you buy. You could try buying either the dob or EQ second hand and give it a good workout, that way you could re-sell it without monetary loss if it doesn't suit you.
