Personal resonance with a game system does not necessarily make it good, or bad, it just makes it not to your taste and/or preference. Which is completely, and utterly, fine. There is nothing bad about disliking a game system. There may even be reasons you personally find a system lackluster, or failing in an area, but this does not in general make a system 'bad'.
All a system is, is a series of rules, to try and interpret our pretendy fun times in a way that doesn't devolve into infantile cowboys and indians/cops and robbers where someone got shot, and another person says they didn't, and the back and forth lasts for all eternity.
The system is supposed to be the impartial mediator. If everyone plays by the same rules, then everyone is in balance, in theory.
The reality is that no system is perfect, there are people who find the holes either accidentally or on purpose, and build to take advantage of the system being ran (Such as multiple action combat merits in nWoD 1.0 for example, or a mentalist in Champions). These can make a system appear to be imbalanced, but everyone is still playing by those very same rules.
Long story short: Different strokes, for different folks.
As to capped vs staggered? I dislike automagic xp. XP is supposed to signify important life altering events that spur a person to change and grow one way or another. It's a mechanic to give the illusion of increased experience.
One can simply do the same job, day in, and day out, and live without truly living, and thus gain no experience. Their skills are static because they aren't being challenged to improve them. They are couch potatoes who spend much of their free time watching the telly.
If you don't have those experiences, then you shouldn't get xp in my opinion.
Also: The only day we stop learning, is when we die (Theoretical soul notwithstanding) thus I am against xp caps.
I also don't believe that some fresh character should be the equal to one who has had all these experiences that have shaped them and made them grow beyond a starting character. It devalues all those experiences.
That's just me.
