Waves vs Lisk, your opinion is appreciated!

So after having bought Verge for 102,48 and having it sold at 308,45 because of the risk of holding one cryptocurrency. I looked further into cryptocurrencies and was making a list of cryptos I wanted to invest in. Currently, the portfolio consists of :

• XEM
• UBQ
• LSK/Waves

I still can't decide to buy Lisk or Waves, both have seen a fairly nice growth over the past month and I would like to hear the opinion of you guys!

How do you guys think I should split the investment and should I either buy Lisk or Waves?
