I've never been fan of this genre; I've only played Fortnite for half an hour and I got bored. I've heard very positive things about Apex Legends though and I decided to give it a try.
In my opinion, Apex Legends isn't just a significantly better game than Fortnite, but it's genuinely a really good game overall. I am quite decent at this game and it is a lot of fun!
The gameplay is amazing despite not being anything special, and it feels very smooth.
The characters are different from each other, some characters can act as support and tank while others are offensive.
The graphics are good and the audio is great.
Also, game focuses a lot on teamplay with some unique mechanics and items for communication; you can even revive your teammates when they die. Teamplay can get a bit frustrating at times, but it's fantastic when it works.
What about the flaws? Well, first of all, there isn't enough content, and secondly, the monetization is a little bit messed up; there are few microtransactions but quite too expensive.

Pros:
+ Fun and smooth gameplay
+ Diverse characters
+ Focuses a lot on teamplay
+ Nice visuals

Cons:
- Not enough content
- Monetization

Gameplay: 9/10
Content: ?/10
Graphics/Audio: 8/10

Final Rating: 8/10
- Great -
Apex Legends is a great game, even though it's lacking content.

Do I recommend it?:
Yes, it's worth a try and it's for free.
