Your use case is why I have iTunes Match. It's finally not buggy, I love it so much it's the reason I got an iPad mini yesterday instead of a nexus 7, and that was a hard decision.
I am all about cross platform these days. S4 GE phone, iPad, MBP laptop, and a windows desktop powerhouse. iTunes Match sucked when I used it last but its been a while.
I've had it since launch, and it's always been pretty buggy. But for the last 12 months all issues I had (libraries getting weird on one device, streaming choking a bit sometimes) have all been fixed, so I'd gladly recommend it now. 18 months ago? God no ;)
iTunes Match would have been a nice feature 5 years ago but there's just no need with the final catching on of streaming. There's still a handful of music not available on Spotify but I find listening to my own collection of songs to be pretty miserable.
