One-time addresses or unique address. Which is better?

[DIGNIDAD]

  It's difficult to say which is better, so let's give a look over their differences and discuss, starting with OT addresses, like bitcoin, the idea is have a lot of addresses and use one in each transaction this addresses can be derivated from a HD wallet, in ethereum we have one address and that is used for everything since spend ether to tokens and deploy contracts. So what do you think?

Obviously one-time addresses are more privacy preserving and more secure.I think that's the biggest issue of ETH.
ETh is unique for it's smart contracts system anyways, not suitable for those who value their privacy though.

One-time addresses are more secure, because each address is used just for once, tracking of funds is harder with one time addresses.

A unique address is certainly good , but the maximum privacy is not achieved, in our world today there are many threats and therefore it is important to keep your address in the shade. So I use one-time addresses , and have one-unique,

bitcoin, ethereum or any other altcoin does NOT matter when it comes to address reuse they are the same: you an do it and there is nothing preventing you from doing so and there are many people, even businesses such as exchanges are doing it. BUT it still has its downsides which you can read here: https://en.bitcoin.it/wiki/Address_reuse

One-time addresses can be considered same with unique, just having an in-built algorithm unique address generator for each transaction. Privacy is appreciated here.

Well in some exchanges and wallets they're offering a unique addresses, like in coinbase which is to avoid being tracked or to make the user be anonymous in this case no one will track you with your transactions but the good thing about this is that you can reuse the address that was given to you.

Well I don't think there's no such thing as one-time addresses, I've been here in the cryptocurrency industry and so far I haven't encountered any wallets/exchange that offers a one time address because it's prone to accident like after you used it you forgot that it was a one time address and you've send some funds there.

I think ETH is a step forward for BTC. The followers always inherit and promote the former.

Both are an inefficient means of privacy. If you use only one address per transaction or re-use one address several times, it is still possible to identify you.
In the end, a wallet is some private keys, so when you send from your it, will be easy to link the addresses of your wallet "if you want to send one bitcoin and have four addresses [0.3/address] then it will be easy to detect that addresses."
The best way is to use one address for each transaction and then use a mixing service, note that the Bitcoin is not built on privacy.
