Sure, it's more grab and go than putting the same 6" SCT on an EQ, but that's mainly because such a scope requires heavier counterweights.
While something like a 130mm Newtonian on an EQ is a bit bulky to carry out the door, it's light enough that you can get the whole thing out to the yard in one trip, maybe two for accessories like eyepieces. You could counterbalance it with half the weight required by a 6SE OTA.
Remember, the best scope is the one you use...
My opinion is that a 130mm Newt would require pretty much the same EQ mounting as a 6 inch SCT. Most of the 130mm EQ mounts which are light are not too good. The minimum EQ mount I'd want is the Celestron CG4 (sold with the Omni scopes). The CG4 weights 21 pounds (same as the 6SE mounted).
The 6 SE tube is around 9 pounds and most 130mm newts are also 9 pounds.
The 6SE with batteries is only 21 pounds. Very lightweight in my opinion. A little awkward if you have the legs extended.
For me, a shaky mount is no fun. So I'd rather use an alt/az mount if I want grab and go lightweight than a low end EQ mount with a larger scope. The low end EQ mounts may work with a 90mm Mak or an 80mm Refractor.
