i wanna pick up akali but how difficult will she be?

for context i currently main qiyana (im iron noob) with around 120k mastery points, and ive wanted to pick up a secondary assassin to play and decided akali due to her not having mana problems (zed was also a strong contender, planning to learn him after akali)

my question is how different is the playstyle for akali/qiyana and how difficult would it be for me to switch?
