I purchased this assuming that it was the best recording around. It gets fantastic reviews and is the recommended recording. However, although it may have some strenghts e.g: the balance is very good and every instrument is heard, it was a disappoinment when I first listened to it - and still is. My preferred version would be the Abbado with the Berlin Phil, it is taken a little slower in areas like the start (which Kubelik rushes so much it loses its depth and becomes just surface music) and the climaxes (Kubelik makes them feel like bars are missing). Kubelik's lacks depth and feeling throughout, as well as dynamic contrast, grandeur, and swagger at appropriate times. Kubelik's is very bland without the blend of styles which apear in Abbado's version.
When composing Mahler said a symphony should encompass the world and I believe this symphony is a product of that thinking. It opens almost like the start to Wagner's Das Rheingold, opening an entire world up to the listener. Then the two middle movements show different corners of the globe before a final struggle and climax in the finale.
To conclude, if you like Mahler to be plain, 2D, and just surface music then buy this. However, if you want depth, contrast, swagger, and grandeour opening up a new world, then buy another version like Abbado or similar.
