Hi guys, could you please help me on purchasing 15" laptop

Below 3.5k
For daily office work.
15" screen
512 SSD


My consideration:
Since (heavy) multi tab browsing + multi app running together would prefer 16GB RAM? (is it overkill?)



Currently looking at these 3 laptops:

1)
IdeaPad L3 15ITL6
i5-1135G7
4 GB DDR4-2933MHz (Soldered) + 8 GB DDR4-2933MHz (SoDIMM)
512 GB M.2 2242 SSD
RM3,008.55


2)
IdeaPad L3 15ITL6
i7-1165G7
4 GB DDR4-2933MHz (Soldered) + 8 GB DDR4-2933MHz (SoDIMM)
512 GB M.2 2242 SSD
RM3,407.55


3)
Machenike MACHCREATOR E
i5-11300H
16GB DDR4 RAM 3200MHz
512GB Nvme SSD
RM3379.00

Would hope the laptop can last at least 5 years.
Which laptop should I take? any other recommendation?
Thanks!!
