Finish Question: Cabot's Australian Timber Oil vs. Epifanes Clear Spar Varnish on cedar table

New EGGer here with very basic wood skills and tools here. I've started with a simplistic version the the Whiz's table plans using cedar.

My essential question: are there pro's or con's associated with either using the timber oil vs the marine grade spar varnish?

Other factors: My table is not 'furniture grade', but rather 'work table grade'. It will be smooth to prevent splinters, but it has exposed screws and since this was my first ever jigsaw cut, my circle is far from perfect. No worries, I'm not out to win a contest. However, I'm looking for minimal long-term maintenance as well as short term functionality with my choice.

My biggest goal is the get the EGG off the ground (paranoid visions of kids playing near it and shattered green-glazed ceramic chunks are waking me up at night!) so that I can truly relax and enjoy it.

Thanks in advance for your thoughts (or corrections to the forum where this is already answered. After hours of Google I've yet to locate an answer!)
