I'd suggest the C14 - stubby, less wind-affected etc for the same capacity mount, easy to thermally equalise & handle in general as well as collimate to a high degree. 
I have an SW 18" GoTo that I have adapted to the same EQ mount the C14 normally rides on but it is so large & bulky that it is rarely used. The 16" version is of course slightly smaller etc but apart from the cost angle would not hold a lot of attraction to me personally...& a secondhand C14 would bring its initial cost down...
As an example, which is a tad conceited
& where I normally just insert a link to our website (in the signature below btw
) here are a few images of the outer planets we've taken over the last 8 years: bear in mind that these are just (really) low-res screenshot jpegs because it's much easier for me to take s/shots off our website than searching for the actual images on my HD's..!
(you can see that from the file-sizes.
)
Saturn was captured in this image 8 years ago with the earliest ZWO120MM camera...perhaps one of the best examples of this planet where clouds & storm spots spring out on the disk as well as a couple of moons, bearing in mind the excellent conditions that night.
The Uranus image goes back to 2014, our first year imaging this Ice Giant & records the large spot others also captured: no reliable captures of such a phenomenon have been seen since by any amateurs btw...
The rest with later model cameras: Neptune in 2015 where numerous BWC's (Bright White Complexes, storm spots) were picked up with one particular spot only imaged & confirmed by the HST which was imaging at around the same time...or as one professional commented <"our own images’ accuracies confirmed almost “point-by-point” in comparison to those of the HST">
Neptune again in 2017 where, despite the Keck team pronouncing "their" discovery of the (hitherto) unrecorded Equatorial storm spots, we had imaged them on 2 occasions before they did, something they later acknowledged because we had lodged our findings at the time with the BAA.
Jove is just a nice image from a couple of years back...as noted above there's plenty of other good images on our website. 
EDIT - oops, also a couple of the Mars images from 2020 at under 50° elevation.
(again, cheap screenshots)
