Condensation and being able to see your seals are not issues (unless you want to see the inside of your housing while it floods), the only issues are price/size/weight/durability. I owned Ikelite housings for about 10 years, first for my N90 and then for my F100 (yes, those are N and F, back in the film days).
Both my ikelites for the film cameras started to develop structural damage (deep cracks) after about 5 years of intense use. I must tell you though that a lot of my dives were between 100 and 150 feet, still well within the limits of Ikelite, but not the usual recreational dives. The aluminum housings are more expensive, smaller, lighter, more durable (Aquaticas are built like tanks) and their controls are more precise (at least when compared to the Ikelites I used).
If you can only afford an Ikelite, then you have already answered your question...
