Define what you facilities, peripherals, and resources you need and compare to the arduino specifications and available shields.
by asking the buyer what s/he/you want and go from there.
Well you start with making a list of your applications or what you want to do with an Arduino project board. Then you look at the current Arduino project boards available and decide what project board works best for your intended applications. You know your applications so you decide what works for you.

Hello,
It just depends on what you need for your applications.
The arduino site has some overviews for you:

And some pictures of the boards:

How do you even know ANY Arduino board is suitable?
Hi,
Determine what functions you need and find a board that can do that.
One of the most important points for a microcontroller or a board with one is how many pins it has. That's because applications depend highly on how many pins it needs. For example if you want to drive a display directly you might need 15 i/o pins just for that. If that display works with I2C however then you only need 2 pins for the whole display. So you see how this works, the pin count is very important.
The basic Arduino Nano and Uno have about 14 i/o pins and 6 to 8 analog inputs with ADC having 10 bit resolution.
The Mega however has something like 70 pins. So you see the difference is quite extensive.
The Due has 12 bit ADC and 12 bit DAC, but it may be being discontinued. You'll have to check into this. It also has something like 70 i/o pins. It ONLY runs on 3.3v not 5v, so it is a little more difficult to interface with 5v peripherals like external ADC boards and LCD displays made for 5v.
There are a lot of other types too but those are the most common.
The Leonardo can also do keyboard emulation on a PC, and the Due can do that too, as well as the Micro.
The Nano is quite small so fits nicely in small enclosures, while the Nano takes up a lot more room, and the Mega and Due take up even more room. Sometimes the size of the board is important too. You can always use two Nano's to get more pins and that still takes up less room then an Uno.
None of these boards including the Due have good Real Time Clock functions however. That is best done with an external RTC board. The Due has built in RTC in the Arm chip, but it's not fully functional because of the way the PC board was designed, and wont be as accurate as a good RTC anyway. The way it is set up as is, when the power goes off the clock stops and when the power comes back it has to be reset again. Adding a battery backup is a very difficult task unless you are very good at SMD rework because the board itself has to be modified.
These are just some of the features and some not so good attributes.
