Submersibles are easier to install, just simply drop them in.
Submersibles take up less room in your stand, but take up room inside your sump.
Submersibles cool themselves by transferring heat back to your tank water....
External takes alittle longer to plumb.
Higher flow rates depending on pumps.
Minimal heat transfer back to tank, depending on pump selection no heat at all.
I personally don't care for submersibles....It's just a personal thing.....I want very little heat transfer, and I can get that with an external and there isn't a submersible that would honestly fit the parameters that I need alot of times.....

How do they compare sound-wise?. Which ones are louder in your experiences?
My only 2 concerns with a pump are noise and flood possibility. Here's my perspective; Internal - no flood/very minimal flood possibility, probably louder. External - very noticable flood possibility, probably more quiet. Am I on the right track?

The noise issue is debateable......I could show you a external that no submersible could touch noise wise and that's the RedDragon pumps, but look at the price tag......Sequence is another....my HammerHead is quiet that you have to touch to see it's running and for the size of the pump that's amazing....Again you get what you pay for at times and alot of stuff can be eliminated....
As far as the statement about flooding issues with external pumps, I feel is totally wrong.. How does the pump have anything to do with flood issues......Your tank floods because of other reasons....blocked overflows, poor planning on back syphon in event of power outage, and all these scenarios can and do happen with submersibles as well......You are at no greater risk with flooding with an external than a submersible.....The bottom line is they are still plumbed back to the tank the same way, just one sits in the sump and the other is outside the sump.....How many people flood their tanks, or rooms because of bulkhead leaks?

Way off base IMO.....they are still plumbed back to the tank the same way, so how is it a greater risk????

First and foremost I should mention that i've never had an overflow or a sump, but soon will. So if i'm being an idiot with my overflow and pump thoughts, rest assured with the knowledge that I may soon flood my apartment. I'd like to think i'm pretty intelligent when it comes to plumbing and water physics though :thinking:
The flooding I was talking about was plumbing fitting related not tank/sump or overflow/bulkhead related. The amount of plumbing and water suspended NOT above a catch (tank or sump) would, in my mind, be greater in an external pump application than an internal pump. I guess the proper term for that would be a "leak" then, not quite a flood.
I wasn't considering blocked overflows or a back siphon, those are basic things no experienced aquarium owner should let happen. But a cracked fitting or a bad seal are hard to catch.
I was picturing a submerged pump with a flexible line straight up into the tank with no more than 2 seams or connections. If water leaked, it'll most likely follow that flexible line back into the sump. Then imagine an external with a bulkhead from the sump to the pump intake, then either a barb to a flexible line or PVC pieces glued together (most common it seems) with many 90 degree elbows and numerous seams/welds/connections/places where you glue 'em together where water would drip if a fitting leaked.
