4130 is a material specification for a tough steel alloy. It doesn't have anything to do with the quality or engineering skill of a manufacturer. 'same with the OX tube. It's basically heat treated/hardened 4130. If you don't use the right amount it don't matter anyway and it's up to the brand manager to figure that out and there are a lot of choices.
When it comes to frame materials it's a matter of you trusting what the mfgr tells you and that they selected the right profile/thickness for the job. If you are a clyde, they aren't thinking about you so try the bike yourself and draw your opinion from that. What may be heavy and dead to someone else may come alive in your hands.
I have an awesome custom bike but spend plenty of time on an old peugeot that just makes me feel fast.
