I went for Samsung Spinpointers because at the time I purchased mine, the T1 166 500 MB had the best price/performance/energy_efficiency. The F1 had some trouble in beginning, but now with latest firmware, these are OK too.

I replace my HDDs every 2-3 years anyway, but I admit 5 years warranty is nice.

It also depends how nice you are to your HDDs. Mine are properly cooled at 30C to 35C (40C in summer).

And, if its important data, you always need at least 1 offsite backup IMO. HDDs are relatively cheap nowadays so there is little reason not to do so.

I also still have many old PATA and SCSI disks being sweet to me.
