I do like Cardano, especially now that the hype has dropped away a bit and prices are more reasonable. But it's still a longshot compared with ETH, which already has a strong history. Yes, Cardano is supposed to offer better tech, but ETH is already somewhat battle-tested and continues to be upgraded. Cardano hasn't yet proven itself enough. Not saying it's bad, just a bit of a big gamble compared to ETH which is also underpriced right now.
