Extensive side by side testing doesn't exist to say which is more reliable. And production variances mean that you could get the one stinker that shouldn't have made it thru QC. There are hosts of posts on that over the years.
Since most guns these days have a few sharp edges and in the pocket pistol class do not operate well with cheap low powered ammo, ten of each gun fired on the line will likely have stoppages and failures until they get thru a few hundred rounds. Once broken in any of them might be "life and death" reliable as long as they are maintained and you shoot them to keep up proficiency. Then, as more thousands of rounds are run thru them - the curve starts approaching a point where wear and tear affect the operation. You never know where you are on that curve years down the road, and you are carrying the gun that shot it's last reliable round when you reloaded it at the range and left.
And, there is the issue - much more important - of just daily carry and getting debris in it, or not having rotated the ammo to always have the fresh round next up instead of the one that has been chambered a dozen times.
All we can share on the net are one gun anecdotal stories of ownership and for all that, it did Ruger no good with the first LCP. They experienced about 6 owner mishaps when they introduced the first generation, reading thru them I never understood where the gun was at fault. Nonetheless they recalled them to change out some parts which they saw as being problematic.
We can't know if that is just 6 months down the road for these two guns. Since there's no way to tell, it's better you choose the one you are more assured of and which you can shoot with more mental comfort it will work. Being confident in it's use means you will likely practice more, and that is going to be a bigger help when the chips are down. There are a lot of guns out there with reputations that are highly disrespected by other shooters but they work for their owners. The problem is that tribal loyalties and Branding get into the selection process - and if there is ever a place to preach about how great somebodies gun is, the internet is it.
To provide an example, I will mention SCCY. Lots of pros and cons about them right now on the net. Yet some consider them their life and death backup. Others would categorically state more the latter than the former. Reading the net the last fifteen years, every gun made has it's fans and haters. Yet they are all carried.
I went thru this last year, sorted out which .380 I might want to carry, and when I boiled down the features, the trigger pull, and where that particular gun was in it's production cycle which means have they fixed the early problems, I wound up with a Kahr CW380. It wasn't really even at the top of the list when I started. Better to go pull triggers and sight down the slides first, see how they fit and what you are willing to put up with. Despite some naysayers claiming my Kahr would be a jammomatic, I find breaking it in on steel cased Monarch fodder it's reliable. And brass cased Hornady works just fine, too.
Your mileage may vary. My first try was a first gen LCP - it was reliable, too, as little as I cared to shoot it or even carry it loaded. Each gun is unique to that owner and it's really up to you to discover what you think about it. That's why there is rarely any consistency on the net about one over the other.
