I've been purchasing my filament from MatterHackers for a few years and have had consistently good results with the economy category. I'm not sure why I'd want to buy the Pro stuff, as the non-Pro pricing is great and the shipping in the USA is free.

If you buy MH filament and get poor results, consider that parameters usually are different from one brand to the next. Your locally purchased stuff may require these adjustments, but your description of the failure is too vague to determine an answer.
