For sharpness it depends on the quality of your converter. I would not waste your money on cheap telecons, as they are usually poor. If you can afford it then stick to Nikon, (but very expensive new, but not so bad 2ndhand), or as an alternative try Kenko Pro.
I use a 2x kenko pro with a nikon 300 f4D lens for bird photos and also have about 6 TC20Es (I sell them on Ebay). Please note these nikon 2x telecons were designed for use with their f2.8 range of lenses and will not work or even fit many of their other lenses.... hence I use the kenko pro. I am unsure what the score is with nikons 1.4x telecons, but you need to consider compatibility with your lens first before even thinking about a nikon.
