The answer:

A tank is easier to clean, easier to keep. Of course it doesn't look as nice as those hamster cages sold with tubes. I have used both cages and tanks and I can certainly give you the pros and cons for both.

A cage with tubes will give you a headache during cleaning. The hamster would pee and poo in the tubes. If you don't clean it right away, it will become crusty and moldy. Also cages does increase the chewing habit of a hamster. It will chew on the bars, causing it to rust. Consuming the rust will cause problems to the hamster's liver and kidneys. Toxin buildup. A cage is of course good when it comes to ventilation, but super messy. Your hamster would dig and kick a bit, and the wood shavings will all come out. Also, the plastic used for cages is of poor quality, unless you go and invest in Critter Trail or Habitrail. The ones that are super colourful and sold at most pet shops are made in China, the plastic is very soft so the hamster chews it easily. Some times it gets ingested and sometimes a hamster can play jail break if it manages to chew a big hole.

A tank is safe. And it is easier to clean if you get the plastic tank. If you get glass, it's good too but just a bit heavy. Ventilation won't be as great as a cage, but you won't deal with messy wood shavings coming out. And your hamster won't be chewing anything metal and get rust poisoning. You can use your own creativity to decorate the tank. A hamster is less likely to escape a tank if it has a good cover on it.

And the best point here.... Syrians don't do well in cages. They are big, so they need a tank size of about 2ft if you can provide it. Cages are normally 30cm.... which is.... less than 1 feet. The tubes can be quite horrible if your syrian is one of those big bone ones. It's difficult to crawl through them. And the wheel that comes with these cages are too small. A syrian can get back problems if their wheels are less than 7 inches in diameter.
