Personally, een through my Canon days with the 5D, 5D2, 5D3, 5D4 I have seen many nightmares and heard nightmare stories from other pro photogs with third party batteries that will always keep me away from them.
To me, a $2500 camera body isn't worth saving $50-$75 on a battery IMHO. I want to ensure I am shooting with the best and most reliable hardware possible!
Any battery has those nightmare stories, all of them are prone to the same failures. Just look at the whole Samsung Note debacle.
I've used off brand (mostly Wasabi Power) batteries in every camera I've owned and in several other devices as well, none have given me a single issue.
As noted by another poster, over time any lithium battery will swell, I've had a couple of my batteries start to do this recently, but I've owned them for years and used them for probably over a hundred cycles, often letting them drain all the way down (which is bad to do with any lithium battery).

Going OEM is always best, if you can. I've used Ex-Pro batteries and find them faultless, I binned my Wabasi ones as two out of three caused my camera to lock up. Saving $50 on a battery will make sense if you have 10 or so in your bag like me.
I'd be very surprised if those lock-ups weren't coincidental. I've had a couple of my cameras lock up before too, and on at least one occasion it was definitely when using an OEM battery. In fact my X-T1 was flaking out a couple of weeks ago with the battery grip on it... I assumed it must be the grip and removed it, camera worked fine after that... when I checked later it turned out the battery in the grip was an OEM battery and the one in the body was a Wasabi Power. It could be that the two batteries were conflicting somehow due to one being not-OEM, but I haven't had the issue again since that day and have tried using the same setup to try and replicate it (I blame it on buying a used X-T1 with grip for $350... who knows how it was treated, but besides that weird random issue it's been working great
)
