overfiltration is always preferred in fish tanks but not always so in planted tanks. Given the turnover volume of the filter, the intake will create a powerful suction, likely affecting the tank inhabitants and the return will likely create too powerful of a current within the tank. In other words, 305 will easily overpower the tank regardless of lily piping or otherwise mods.
The Fluval 305 had some reported flaws in design which were reengineered in the 306. The priming system now works, the aquastop valves are less likely to leak and the lock clamps were improved. I cant recall how many times my clips broke on my eheim canister over the years, though it had served about 5 years of duty.
This all comes down to personal preference and of course budget. a basic HOB may do all that you need for under $30. shouldnt need to spend too much money on filtration for a planted tank. You'll likely want to make sure water is being circulated while the plants do their work on the nutrients in the water column...
