I play a ton of Destiny but I pretty much avoid its PVP components like the plague. It's never really been particularly well-balanced but it's gotten to the point now where it's just a clusterfuck of people running around with one-hit-kill abilities/weapons, Stasis which has even further fucked things up, etc. I think even Halo 5's PVP takes more actual skill and is better balanced, and I fucking despise Halo 5.
And I'll be honest, I've never really gotten the "it feels like Halo" thing in regards to Destiny. To me, it's always played more like "Call of Duty: Magic Warfare".
I've played them all. Killzone was always very mediocre to me, and in my view was almost 100% carried by its visuals. Shadow Fall in particular was a brutal slog that I was begging to finally end. I think my favorite Killzone was actually the Vita one, but Sony shut the devs of that game down, because of course they did. Resistance I think I liked more but it still wasn't anything mindblowing. 2 was probably my favorite but I believe I'm in the minority on that. Haze was just fucking awful, I played it years ago for about 20 minutes and that's all I could take.
In more relevant news, it looks like Infinite is getting another update this week, although not as big as the last one.
