ADDITION: (February 2019) Koch - Region 'B' - Blu-ray: This Koch is a good release! It initially offers either the 1.33:1 version or the 1.85:1 widescreen. These are separate transfer on the dual-layered disc and they are technically very similar in that they have the same high bitrate. The image quality looks quite good - no blemishes and nicely layered contrast. Detail significantly rises - especially over the Screenbound DVD. There is depth and overall the Russell Metty shadows and light usage looked very impressive on my system.   

Koch offer both the original English-language track and a German DUB both in 16-bit linear PCM tracks. Effects are not abundant considering the sci-fi nature but the score is often dominant in establishing moods. It in itself is quite aggressive. I couldn't find a credit for the score but it may have been Universal music director Joseph Gershenson who had received executive producer credit on some films of the 1940s, but Monster on the Campus marked the first film for which he received sole credit as producer.  The BD includes optional English or German subtitles and th Blu-ray package is Region 'B'-locked.

Supplements include two Jack Arnold interviews - of about 1/4 hour each where he discusses his career. He seemed quite soft-spoken. There is also a German and English Trailer plus an image gallery.

Monster on the Campus is another of those quintessential 50's creature features. I love them. The Blu-ray is a very pleasant surprise as the image quality is so strong, has the option of widescreen and has decent audio and Arnold interviews. Heck yeah! - I am glad to own this.

ON THE DVDs: Unfortunately, the Screenbound Entertainment source is inferior. It's single-layered, as is the Universal, but looks quite soft beside the US edition (as found on both Classic Sci-Fi Ultimate Collections.) Not much more to add. It has PAL speedup and looks less-sharp beside the US transfer. On the positive it is consistent in-motion but may be marginally boosted. I always wondered if this was widescreen theatrically...

Audio is consistent without major flaws. There are only optional subtitles on the Universal. Extras consistent of a trailer (both) but the UK includes a superfluous gallery.

So it's drawbacks against the Universal are the PAL speedup, no subtitles and the, essential in my mind, US set offers so much value. Those less concerned about image quality, subtitle requirements or the 4% PAL speedup, and who may not already own the Classic Sci-Fi Ultimate Collections (or find it too pricey) have an option in the new Screenbound release.
