Keep in mind, reliable talent doesn't raise the ceiling on skills, it just raises the floor.
And it raises the floor by 45%, 9 points on the d20. It's twice as good as Advantage in that way. More, it raises the floor from - assuming a Proficiency Bonus of +4 and a stat bonus of +4 and no Expertise - 9 to 18 and 18 is often a success.
Heck, in a campaign where the DM uses passive skills, and uses the passive skill score as a floor - the ability becomes much less useful.
That's effectively giving everyone Reliable Talent.
