Personally neither are great in my opinion. In the first the two letters overlap too much resulting in an unclear use of the letters, think of the logo at 1/4 the size, would it be recognisable? With the second logo it looks like you're trying to convey a meaning to it but for me I cant see what the logo is supposed to represent. Lastly the grey is well grey, its very dull and will never grab anyone's attention, use a vibrant colour. Go back to the drawing board, research logos in the design industry and use those to influence your own.
