The SW200 is in a different league to the NH35 and the 4R and 6R Seiko movements for that matter. A new SW will have an amplitude over 300 and typically around 4s/d variation over five positions for the standard version, whereas an NH is usually around 270 amplitude and average around 12s/d variation.
The NH is still a decent movement, but they tend to be poorly assembled and regulated with pallet pivots being oiled and a lack of oil or too much on the other pivots and jewels. Often the beat error is way over 1ms (it should never be more than 0.5ms in any position) but the rate is good, which suggests a 'that'll do' attitude during adjustment which is likely encouraged by the pathetic -30/+40 s/d standard spec they have to aim for. Then there are things like the hairspring being incorrectly bent which exaggerates positional errors and I've seen a couple where the wrong screws have been fitted on the dial side and are pressing on the setting lever, so when you try to adjust the time the crown comes out in your hand.
The SW on the other hand usually arrives with beat error at 0 or 0.1ms and a few seconds per day accuracy on the wrist. There's fine tuning adjustment on the regulator too so if it does need a tweak it's quick and easy to do, as opposed to the NH where you can spend 20 minutes moving the regulator arm back and forwards before it finally lands where you want it.
One place the NH is superior is the auto winding with the pawl lever teeth only really wearing if moisture and corrosion gets in. The SW200 reverser wheels can be a weak point if not lubricated and often need replacing during servicing, but apart from that it blows the NH out of the water and is well worth paying more for, IMO of course.
