Traffic Index Vs Customer Capacity

I am having a dilemma which building i should rent. I have 2 options currently both in Midtown with the first building have 44 Traffic Index and 30 Customer Capacity, the other building is 20 Traffic Index but have 75 Customer Capacity. Help me with your suggestion which building i should rent.

If you want the highest profit, you can:
The first thing to consider is the region, as this will determine the pricing of your product.
Secondly, the Customer Capacity is greater than the Traffic Index. I would rather choose 20 Traffic Index + 75 Customer Capacity.
Finally, the impact of the Traffic Index on daily passenger flow is 5 - 10 customers ( M1 Sotre ) .
The above is based on my game experience, I hope to help you!
