The question as asked is unanswerable. Literally it depends. And it depends on a lot more than the 'brand' with these types of bikes. It depends on the day of the week, the phase of the moon ... seriously. Pick two department store brands and chances are good both were made at the same factory! So the only difference is what kind of day the guy who spot welded the bottom bracket was having. If not so good your frame may fail there one day. Or not. If you want to buy a cheap bike or bike frame buy the one that appeals to your eye the most. Call it good. Why make it any more complicated than that?
