Good to own both. But, if to choose, right now I would take ETH. Because of upcoming fork, possible price pump, and there are something more how ETH 2.0. Will suprise us
I will choose ETH for another reason. This coin is relevant both in investments and is required for transactions (gas) and is the king of projects. A lot of things in the world of cryptocurrency performs on this better look to her. But of course the choice of each.
Well I think both coins are good for investment, of course eth is more popular than ltc, but now they are in good shape to take them and make money on them
