The other one does not seem to be so good, although I haven't tried it that much to be certain.
And the pdfs I am currently using are professionally built as large book chapters (120 pages) with dense text and figures. It takes quite some time to open them the first time, but afterwards everything is acceptable in terms of time.
N.B., it seems to me that the CIS 2.1.2 firmware makes PocketBook 912 a bit slower and unresponsive (e.g., pages do not always change when I press the forward button). Still, this is nothing compared to the bad display quality I had before.
