Choosing between single-dose coffee grinders is less about finding one universal winner and more about deciding which details matter at your counter: an explicitly electric format and adjustable settings, or a grinder with a named burr size, setting count, and capacity. The VieSimple Gen 4 and HiBREW G5 are both burr grinders aimed at single-dose espresso, but they frame that choice differently.
Quick verdict
Pick the VieSimple Gen 4 when an electric burr grinder with adjustable grind settings is the priority and the lower $129 price suits the plan. Pick the HiBREW G5 when you specifically want the 48mm conical burr and 36-setting configuration named in its title, plus a 50-gram capacity and easy-clean feature. The price difference is $40, so the decision hinges on whether those G5 specifications are central to the way you shop for coffee grinders.

Where each product wins
VieSimple Gen 4 wins for the lower entry price and explicitly electric format. Its single-dose espresso positioning and adjustable grind settings make it the straightforward choice for someone who wants those phrases clearly attached to the grinder.
HiBREW G5 wins for shoppers seeking a more specifically named configuration. The G5 title calls out a 48mm conical burr and 36 settings, while its 50-gram capacity, easy-clean feature, and lightweight wording give a shopper more concrete characteristics to prioritize.
Both fit the shared core brief. Each is a burr coffee grinder with single-dose and espresso language, so neither has an automatic advantage simply for targeting that style of coffee preparation.
Product notes
VieSimple Gen 4 Electric Burr Coffee Grinder

The VieSimple Gen 4 is a sensible fit for a shopper who wants an electric burr grinder expressly positioned for single-dose espresso. Adjustable grind settings are part of its stated design, giving the buyer a clear reason to choose it over a grinder with no adjustment wording. Its compact design language may also be appealing where counter space is part of the decision. The main limitation is specificity: a shopper set on a product named with a 48mm conical burr and 36 settings will find those exact details in the HiBREW G5 name instead. Treat the VieSimple's adjustable settings as a useful general feature, not as a direct numerical comparison with the G5's 36 settings.
HiBREW G5 Single Dose Coffee Grinder

The HiBREW G5 is the more targeted choice when the 48mm conical burr and 36 settings are on the shopping list from the start. Those details are stated directly, as is its single-dose espresso focus. A 50-gram capacity adds another concrete specification for buyers who want to factor capacity into their choice, and the easy-to-clean and lightweight features may matter for everyday handling. The limitation is the $40 higher price than the VieSimple Gen 4. That difference does not establish a performance outcome, but it does make the G5 a more deliberate purchase for someone who specifically wants its named burr, settings, capacity, or cleaning-related feature.
Final choice by use case
Choose the VieSimple Gen 4 for an electric, single-dose espresso burr grinder with adjustable settings at USD 129.00. Choose the HiBREW G5 if a 48mm conical burr, 36 settings, 50-gram capacity, and easy-clean wording are more important to your decision than the higher USD 169.00 price. For shoppers focused simply on a burr grinder for single-dose espresso, both meet that brief; the deciding details are electric operation on the VieSimple side and the G5's more specific configuration.
