Is the meaning the same or is infinitive preferential for showing habit?
When I pour tea I like to put the milk in first.

There really is no difference in these two because this is a casual statement and people don't really think too hard about these types of things when speaking. However, if pressed, I would say that to put focuses more on your habitual order of doing things, while putting focuses more on the pleasure you receive by doing it.
After a certain number of verbs you can use to-infinitive or gerund with almost the same meaning. Verbs of perference (or non-preference) such as
belong to this group. Also

In my opinion, gerunds represent habits and things you enjoy regularly. I base this on the "ing" which for English speakers represents action now.
I feel that Infinitives represent potential and possibilities. One place you can find this is in Hamlet's soliloquy. He doesn't say "being or not being," he says "to be or not to be." He also uses the infinitive in 9 other places in that soliloquy. The context helps give the infinitives the meaning. I strongly feel that research into visual imagery created in the brain when hearing sentences would demonstrate this.
As was pointed out in another post, trying to figure out the difference in meaning with isolated sentences like this (or ones which are "locked", meaning it is not really possible to add more to the sentence) is an exercise in futility because there is no context. Putting the sentences into a context or creating a reason for saying them would help differentiate the meaning. "When I pour tea," is not a meaning or a context. When you pour tea at Grandma's once a year? When you pour tea every morning with breakfast? When you pour tea for the Queen if she should visit you?
I also think that speech mirroring affects choice of words. So, if someone asks "What do you like to do?" a speaker will unconsciously mirror and say "I like to..." Same with the gerund.
