I'd much rather be in NXT than LTC that's for sure. Look at all the amazing features NXT has over BTC. What does LTC have over BTC? A different graphic on the QT wallet and a little bit quicker transaction times.
The only reason LTC got as high as it did is because it was one of the first alts. Once the alt market became saturated, there were just too many better choices than LTC for people to invest in.
