you sure you are talking about the dash wallet shokdee? it is only 1.14 gig which is one the smallest in the top 10 as far as i know. i think monero is about 10gig and it launched after dash and just now got a official gui and people starting to really use even use it, hate to see how that's going to scale. doge has massive bloating issues too at almost 20 gigs along with ethereum (less than 1.5 years old) at around 75 gigs (oh my) and btc over 100gigs.
if you download the dash bootstrap it should take just minutes.

the current dash gui is not a fancy as others i have seen but gets the job done and is user friendly. bitshares had a real nice gui but it was pretty complicated and not very user friendly. it had an embedded exchange and all kinds of cool features though. i sold all my bts long ago and don't know how they have progressed, nice pretty gui though.

check out the Dash evo wallet it's pretty, professional and easy to use. you will not need to dl the whole bc either but will get the same level of security as if you did.
