Is it better? Just how long is a piece of string? Either will outperform what you ask of it during normal use. To get the best use a tripod and a cable release. Most 'bad' performers were wrongly accredited, simply because of camera shake.

Most Pentax lenses, especially the mulitcoated ones were good. Over the years I have had a chance to try a lot of them out and really have not found one that I could describe as poor.
The 200mm F4 was not the strongest of the bunch but good enough to give me a 12x16 mono print and that is all I ask of it. The 300mm was certainly a good lens but on the heavy side. I have not had the chance to use one of the 20mm F4 offerings but I have seen results from them and they were as good as anything else on offer at the time they were manufactured.
All the others were better than just plain good.
