So, Soulstealer Vladimir or Blade Queen Lissandra?

Note, I haven't posted in forums in forever, the last time I did, it was on the old league website. Please go easy lol, let me know if this doesn't fit here c:

But anyway, should I get Blade Queen or Soulstealer? Soulstealer is going to be on sale soon (its almost been a year) while Blade Queen Lissandra is on sale at the moment. I feel like they're pretty similar (green particles, green model etc.), but I only have enough RP to buy one of them on sale. So, what are your thoughts on these two skins? I play both of them frequently. It would be great to hear your opinions on these two skins!
