Expandability, DS1813+ are more value for money.
The price different for DS1513+ and DS1813+ is RM700. While DS1813+ and DS2413+ is 1500.
If you look at price per drive bays, the most value for money would be the DS2413+ (RM 433 vs RM 462 for the DS1813 vs RM 600 for the DS1513+).
But of course since 8 drive bays would probably be most adequate for most users, the DS1813+ is a better buy.

Read/write 1513+ and 1813+ is about the same. While 2413+ is lower. Energy consumption for 1513+ - 51w, 1813+ - 75w and 2413+ - 111w.
Quoting those power figures alone is an unfair comparison. Those figures take into account that the unit is fully loaded i.e. 12 drives running in DS2413+, 8 drives running in DS1813+ and 5 drives running DS1513+. If you divide them accordingly, you'll see that per drive they consume around the same. I would assume all 3 units itself without hardisk consume around the same amount of power since running on the same Intel D2700 processor.
Concerning the read / write throughput of the Synology units, what they don't tell is how they achieve it. It's through bonding of the Gigabit LANs on the Synology units. But they also forget to tell you that you need LACP compliant switches (managed) to be able to
I'm currently using 2 Gigabit LANs on my unit in bonded mode. From one PC to the DS2413+, I don't achieve the close to 200MB/s writes across my Gigabit network as advertised. I will only achieve those write speeds when I have another PC writing to the DS2413+ at the same time and the total of the 2 PCs (or more) minus some overheads will be close to the advertised write speeds. Like wise the same for the read speed. So far I know I'm mostly alone on my network and not possible for me to be doing 2 things at different PCs on the same time in the network to take advantage of LACP. So more read / write speeds on the DS1813+ and the DS1513+ with 4 x Gigabit LANs bonded, though nice to have, does not give additional benefit for normal home user. If you have 2 or 3 power users running on the same network, then perhaps it's worthwhile.
But I digress about LACP... For my usage, I find the DS2413+ more convenient since there's room for expansion all under one housing.
