SumatraPDF is way better.
PDF readers have, over the years, managed to earn themselves something of a reputation for being slow, lumbering beasts - thanks largely to Adobe Reader. Sumatra PDF bucks the trend. It is small, svelte, lightweight and lightning fast.
Always prefer SumatraPDF. Loads nearly instantly.
I use SumatraPDF and I love it. The reason I like it is because it allows for customization I need, remembers recent location in books and documents, it's free, and it's open source.
I like SumatraPDF. Runs the circles in terms of performance around the sad piece of crap that Adobe PDF Reader has become.
+1 for SumatraPDF. Fantastic application.
Been using it for years, ever since Foxit Reader turned into whatever it is now.
If your Adobe reader croaks or feels glitchy while scrolling, try Sumatra PDF instead. It will be almost like opening a plain text document. Plus you can easily highlight text.
I love Sumatra PDF, thank you for making it.
I'm a big fan of SumatraPDF and use it everywhere I can.
I am pretty happy with SumatraPDF on Windows. Orders of magnitude faster than Reader too.
Sumatra PDF is the best.
I like Sumatra PDF. It's speedy, lightweight, and gets the job done.
I used to use Foxit, but have since turned to SumatraPDF. It seems to be a little lighter weight than Foxit.
SumatraPDF is one of those amazing open source programs that does everything a closed-source and/or commercial product does, but better in every way.
You can customize and read about every possible document format out there with SumatraPDF, it doesn't take your resources with useless UI and that's good if we are thinking about what lightweight means.
