Two sales advice exerpts are conflicting from 2 different sources. Which do yall think is better?

1: Sabri suby says to approach it like this: “Ok cool are you available x at x for a meeting?”

“dont ask them to pull up their calendar and look for an available time slot with you because it is making them work & do things for u. People will have a higher chance of agreeing to the meeting if the entry barrier is even lower. So instead, give them options." “When works best for you-This week or next?..” (wont this create shitty appointments where they are probably not even gonna show up though?)

"Ok great, tuesday or thurday?

Awesome, morning or afternoon?

Awesome, 2 or 4 pm?"

2: Jeremy miner says to do this:

(this exerpt is from him handling a fake objection, (not the real objection deep down) "I just need some time to think it over/ think about it" )

Jeremy: Yeah john… look thats not a problem… now whats your time frame on getting back to me in the next day or so just to see if i’d be available for you

Prospect: "probably later this week" (this dull response means hes not really that interested according to him. A more interested response would be "today or tomorrow 2-4pm)

Jeremy: "Well.. i mean im not sure if id be randomly available like that with my schedule, what i can do though- if it helps you- is if you have your calendar handy, i can pull up mine and have you book a specific time with me, that way you dont have to chase me down and vice versa. would that help you if i did that? " (he uses this approach because it makes the sales person look like a busy guy, that handles alot of incoming business and makes him look in demand/ an authority)

And it Lowers their gaurd because it makes them think ur gonna get off the phone now- which is what they want- and removes the sales pressure

My question is, did jeremy only use that type of strategy there because of that situation, or should i always ask for them to get their calendar and act like im busy and create urgency like that too? Or should i go with the other route? Im asking this to learn how to act in cold calls. Or is this info more for demos, discovery calls, or inbound leads instead?
